I've read #241 and tried the following command to see if it can solve my problem, but it fails.

mv $TMPDIR/localstack.ddb.zip $TMPDIR/localstack.ddb.old.zip
pip install --no-cache --upgrade --user localstack
localstack start

I add --user option because I'm using macOS. (see #248 for how to install localstack on macOS)

It seems like that the error has something to do with DynamoDBLocal.jar. Because localstack cannot find this file.

Anyone knows how to solve this problem?

The text was updated successfully, but these errors were encountered:

thesurlydev · 2018-02-02T20:29:07Z

I had the same issue on Ubuntu. I had to do the following then reinstall localstack to get things working:

rm -rf /usr/local/lib/python2.7/dist-packages/infra

whummer · 2018-02-04T22:10:53Z

Thanks for reporting @lyenliang . This looks like a transient installation error, for some reason the elasticmq-server.jar and DynamoDBLocal.jar files were not downloaded properly. Can you please try the fix suggested by @digitalsanctum :

rm -rf /Users/myName/Library/Python/2.7/lib/python/site-packages/localstack/infra

zar777 · 2018-05-21T14:30:22Z

Hi,

I have the same issue but when I run localstack inside the docker container. If I try locally instead, it works fine. Any suggestions?

petrogko · 2018-05-30T12:39:37Z

I have a similar issue while attempting to start kinesis on localstack within docker container.
There are no ports with 4565 being consumed.

UPDATE*
For me this was thrown, and I'm not sure as to why, but - DATA_DIR="/tmp/localstack/data" was responsible for this error.
This was part of the docker-compose.yml file.

tai2 · 2018-06-19T05:34:21Z

Same here.

In my case, it only occurred when launching all services and data persistency enabled.
So I tried to launch service only I needed, which is S3, then the error was disappeared and localstack successfully works.

bismark · 2018-07-17T20:19:48Z

In case it's helpful for anyone, I was getting this error when running with DATA_DIR and found the issue after running with the --debug flag:

I was able to resolve it by running npm install in <path to site-packages>/localstack.

on running command 'localstack start' it ran fine but when I hit any url like dynamodb localhost:4569 it throws error as shown above.

@lyenliang After a lot of time waste looking everywhere for the solution I found the following.

Note: I'm using Win10 and WSL, I can't guarantee would be the same on a genuine linux distro.

After installing nodejs, npm, pip, java and localstack using:

pip install --no-cache --upgrade --user localstack

when running localstack start I had:

2018-07-18T14:03:29:ERROR:localstack.services.generic_proxy: Error forwarding request: HTTPConnectionPool(host='127.0.0.1', port=4564): Max retries exceeded with url: ...

Using DEBUG=1 localstack start
I had between other debug lines:

[...]
Starting mock SQS (http port 4576)...
Error: Unable to access jarfile DynamoDBLocal.jar
Starting local Elasticsearch (http port 4571)...
[...]
Starting mock Lambda service (http port 4574)...
Listening at http://:::4565
Error: Unable to access jarfile /home/danver/.local/lib/python2.7/site-packages/localstack/infra/elasticmq/elasticmq-server.jar

Reading around I found that there are some files that have to be removed before reinstalling localstack. My problem was that none of the path indicated was existing in my environment
So I decided to have a look under /home/danver/.local/lib/python2.7/site-packages/localstack/infra that was indicated in the error message.
There I found these files and folders:

danver@Danver:~/.local/lib/python2.7/site-packages/localstack/infra$ dir
dynamodb  elasticmq  elasticsearch  localstack-utils-fat.jar

I decided to remove the whole infra directory using:

rm -rf /home/danver/.local/lib/python2.7/site-packages/localstack/infra

And running again DEBUG=1 localstack start, in the middle of lots of debug lines I found Ready. but also:

Error: Invalid or corrupt jarfile /home/danver/.local/lib/python2.7/site-packages/localstack/infra/elasticmq/elasticmq-server.jar

For now I don't need ElasticMQ, but obviously there are still some problems with that .jar file.

I can confirm that now when hitting localhost:4569 gives:

ERROR:localstack.services.generic_proxy: Error forwarding request: expected string or buffer

I believe this is a problem with the parameters of the get request maybe, isn't it?

Last update

I can say that despite of this error:

ERROR:localstack.services.generic_proxy: Error forwarding request: expected string or buffer

I send commands to DynamoDb, S3 and API Gateway using AWS cli and receive correct responses. So, everything seems working perfectly
Maybe the problems is as mentioned before:

I believe this is a problem with the parameters of the get request maybe, isn't it?

I had this issue also and even after deleting the infra directory it still happened.

I'm running on Mac and found that the files were in the tmp directory under /var/folders/<path>/T

To find them just run:

find /var/folders/ -name 'elasticmq-server.jar' 2>/dev/null
find /var/folders/ -name 'localstack.ddb.zip' 2>/dev/null
find /var/folders/ -name 'localstack.es.zip' 2>/dev/null

Delete these files and the infra directory and then run localstack start and it should download the files again and set it up correctly.

sotayamashita · 2018-11-28T04:24:43Z

I solved the issue to delete the image and pull again. I hope it helps you 👍

docker(18.09.0)
localstack (localstack/localstack:latest as 2018/11/28)

EmilOJ · 2019-01-03T18:55:31Z

I solved the issue by installing on JDK 8 and maven (my bad for not reading the prerequisits properly).

MacOS 10.14.2 (Mojave)

brettcooper · 2019-02-18T19:18:54Z

I was having this same issue and simply deleting the local data/ folder mapped by $DATA_DIR, then starting Local Stack again fixed this problem for me.

zar777 · 2019-02-19T10:05:54Z

I solved the issue. Basically I was zipping a file during the container initialization and that was causing me issues.

edwards-will · 2019-05-25T12:54:17Z

In case it's helpful for anyone, I was getting this error when running with DATA_DIR and found the issue after running with the --debug flag:

$ SERVICES=kinesis DATA_DIR=/tmp/localstack/data2 localstack --debug start
Starting local dev environment. CTRL-C to quit.
Starting mock Kinesis (http port 4568)...

<path to site-pacakages>/localstack/node_modules/levelup/lib/leveldown.js:31
throw requireError(e)
^
LevelUPError: Failed to require LevelDOWN (The module '<path to site-packages>/localstack/node_modules/leveldown/build/Release/leveldown.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 48. This version of Node.js requires
NODE_MODULE_VERSION 59. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).). Try `npm install leveldown` if it's missing

I was able to resolve it by running npm install in <path to site-packages>/localstack.

Got the error after upgrading to a new nodejs version and for me, the solution was npm rebuild but this was the solution :)

Thanks all for posting the solutions here. Closing this issue as outdated/fixed. Please open a follow-up issue if the problem persists. Thanks

sullivandl · 2020-12-18T19:21:09Z

I'm behind the times, but hit this issue on MacOs and resolved with:

docker pull localstack/localstack
