GCP Cloud Function - ERROR fetching storage source during build/deploy

Question

Running into problems building deploying functions. When trying to programmatically deploy the function I get the following output in builder logs (ERRORS).

Confusingly, if I deploy the function from the UI, it builds/deploys fine. That makes me think this is some sort of IAM/permissions around the builder/agent. But, am rather lost. Any tips/thoughts? Thanks!

Answer 1

Had the same error message after spending a day troubleshooting I finally found a way.

I noticed I had node@15 installed on my PC and node@12 for firebase function.

All I need do was to

• install node@12 on my PC
• unlink the previous node (i.e node@15) and
• link to the newly installed node@12.

Boom! it uploaded.

Answer 2

I had the same problem deploying cloud functions on my newly started Firebase projects. My local version of node was 15

For beginners (like me) which were struggling downgrading node on Mac, you can use the following commands:

sudo npm install -g n
sudo n 12

Answer 3

As Prodigy mentioned, something must has broken the Cloud Functions deployment in the latest Node v15.6.0 (or another recent one).

Has the same issue today with firebase deploy. Resolved by rolling back to Node 12 (and I am sure any other more recent version works great).
