Hey @tahir606, thanks for reaching out and sharing your debug logs. I’m able to reproduce the error you mentioned. From what I can gather, it occurs when at least one of your env variables doesn’t have a value set, resulting in it being undefined. I’ll raise this to our engineering team to see what we can do here.

Thanks @aalej, That is great to know. What would be the solution here? Setting a value to the env variable? And if so how can I find out which one is it?

Because when I do firebase:config:get I get the complete object with all the envs.

That's interesting, I was under the assumption that firebase:config:get was returning something like:

{
  ...
  "my": {
    "test": {}
  }
  ...
}

Got the config above by running firebase functions:config:set my.test.id=. Setting the value of the variable should fix the issue. Any chance you could share an overview of the output of running firebase:config:get? Please change the string values in the output to remove any personal identifiable information.
