I have a bad response 301 error on the getImage() function

This cloud function was running fine for months.

{ Error: Bad response status code 301
at ClientRequest.handleResponse (/srv/node_modules/plotly/index.js:237:25)
at Object.onceWrapper (events.js:315:30)
at emitOne (events.js:116:13)
at ClientRequest.emit (events.js:211:7)
at HTTPParser.parserOnIncomingClient [as onIncoming] (_http_client.js:552:21)
at HTTPParser.parserOnHeadersComplete (_http_common.js:119:17)
at TLSSocket.socketOnData (_http_client.js:454:20)
at emitOne (events.js:116:13)
at TLSSocket.emit (events.js:211:7)
at addChunk (_stream_readable.js:263:12) msg: undefined }

I have not changed anything in my code base.

Is there some type of service outage?
