Call a Gen-2 GCP Function

Question

I have deployed the following 2 functions on GCP Cloud Function: gcloud functions list

#1

NAME: myfunction-no-01
STATE: ACTIVE
TRIGGER: HTTP Trigger
REGION: us-central1
ENVIRONMENT: 1st gen

#2

NAME: myfunction-no-01-gen2
STATE: ACTIVE
TRIGGER: HTTP Trigger
REGION: us-central1
ENVIRONMENT: 2nd gen

I tried to call both functions from the CLI on the browser, but the gen-2 function (#2) doesn't work.

ERROR: (gcloud.functions.describe) ResponseError: status=[404], code=[Ok], message=[Function myfunction-no-01-gen2 in region us-central1 in project my-project does not exist]

Could anyone please enlighten:

• How does one call a gen-2 function?
• Can I call a gen-2 function from the CLI?

Answer 1

You have to use --gen2 while calling gen2 functions. The command should be like below

gcloud functions describe myfunction-no-01-gen2 --region=us-cental1 --gen2

Have a look at this documentation

And make sure gen2 function is exists in specified region
