firebase serve Getting "⚠ functions: Cannot set property config of #<Object> which has only a getter ⚠ Your function was killed because it raised an unhandled error."

[Sreedar Raju]

Hi Experts,

I am getting the following error when I try to run firebase serve. I think it started happening after I ran npm -i firebase-functions@latest. Can somebody please shine their light of experience? I am really getting pushed and frustrated with this - 

The same code is working when deployed to test site, but locally I get the error. Help!!

Hi Sreedar,

This was a bug in version 8.4.0 of the Firebase CLI.  Upgrade to 8.4.1 to get the fix.

Hi @Raju,

As the error suggested it is issues with node version. You may try by upgrading your node version.

Thanks,

Sohel
