Where did the error occur? http://localhost:8181/admin#/activities
Which release did the error occur in? 3.4.1
Frequency of occurrence 4 times (Can be done many times as I will mention the steps to replicate this issue)
Additional context Add any other context that would be useful. Make sure to anonymize user data like user IDs, exploration IDs, state names, user names, etc. Replace any personal data with appropriate placeholders.
Reproduction steps:
- Go to admin page .
- There is a option to add number of explorations add 1000 exploration and this issue might occur.
- If it is not shown in the first try ,try adding 1000 exploration again .
General instructions for contributors
In general, the procedure for fixing server errors should be the following:
- Analyze the code in the file where the error occurred and come up with a hypothesis for the reason.
- Based on your hypothesis, determine a list of steps that reliably reproduce the issue (or confirm any repro instructions that have been provided). For example, if your hypothesis is that the issue arises due to a delay in a response from the backend server, try to change the code so that the backend server always has a delay, and see if the error then shows up 100% of the time on your local machine.
- Explain your proposed fix, the logic behind it, and any other findings/context you have on this thread. You can also link to a debugging doc if you prefer.
- Get your approach validated by an Oppia team member.
- Make a PR that fixes the issue.
