部署时“执行：查找[程序包]”错误3

Question

I am trying to deploy a Go cloud function. I successfully deployed this function to one GCP project, but now when trying to deploy it to another I can't seem to get it to deploy.

I use this command to deploy the function:

gcloud functions deploy Generator --entry-point Generator --memory 512MB --region europe-west1 --runtime go111 --trigger-event google.storage.object.finalize --trigger-resource gs://[redacted].appspot.com --project [redacted]

I am using a go.mod when deploying:

module gitlab.com/[redacted]/[redacted]/[redacted]

require (
    cloud.google.com/go v0.35.1
    firebase.google.com/go v3.6.0+incompatible
    github.com/tdewolff/parse/v2 v2.3.5
    golang.org/x/net v0.0.0-20190125091013-d26f9f9a57f3
    golang.org/x/text v0.3.1-0.20180807135948-17ff2d5776d2
    google.golang.org/api v0.1.0
)

I get this error message, which is cut off at the interesting part so I can't see what the actual issue is (I think).

How do I get the function to deploy?

Answer 1

After contacting Google I have figured out what the issue is.

The issue is a combination of an error character limit of 4096 characters in Google Cloud Functions wrapper and an artificial timeout for go mod downloads imposed by Google.

The issue can be resolved by vendoring your dependencies as explained here: https://cloud.google.com/functions/docs/writing/specifying-dependencies-go#using_a_vendor_directory
