[REQUIRED] Actual behavior

We had this issue suddenly, I thought it was a service outrage but it seems not , all our cloud functions are returning this warning.

I removed all of the cloud functions and disable the cloud API but it did not work.

Were you able to successfully deploy your functions?

Yes, the deployment works fine

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

A quick update, we did a manipulation on IAM, we needed to add Cloud task enqueuer as a role, couple of min after we got this issue.

We removed the role but the issue persists.

@DMZakaria Did you finally solve the issue? I'm having the same problem.

@erikmartinjordan No, I created a a new environment and migrate my project

Sorry you had to migrate to a new project to get the issue resolved.

Q: Did the values you store in functions.config().firebase change for any reason?

Since migrating to the project seems to have resolved your issue, and there hasn't been any changes to the functions.config(), I suspect that its either firebae admin sdk or some other external changes like IAM settings. Please re-open the issue if you continue to have problems.
