ApiRequestError: Request failed when using client.v2.streamRules()

[SmartArray]

Hey guys, my twitter bot was always running very well in production until recently it just stopped working.

I initialize my client using a bearer token (v2).

When calling client.v2.streamRules() I get this exception:

ApiRequestError: Request failed.
    at RequestHandlerHelper.createRequestError (/app/node_modules/twitter-api-v2/dist/cjs/client-mixins/request-handler.helper.js:57:16)
    at RequestHandlerHelper.requestErrorHandler (/app/node_modules/twitter-api-v2/dist/cjs/client-mixins/request-handler.helper.js:216:21)

    at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
  error: true,
  type: 'request'
}

I also tried to investigate into the hidden .request property but it didn't give me any evidence.

The weird thing is that it works very occasionally so I put the call into a while loop with a period of just over 60 seconds, hoping it will work sometimes.

Anyone knows what could be the reason for this failure?

Thank you so much in advance!
