Deploying functionbeat on GCP with entry point `RunPubSub` returns an error complaining about storage entry point, which I am not using.

I get the following error upon deploy

```auto
Deployment failure:
Build failed: # functions.local/app/main
src/functions.local/app/main/main.go:43:21: undefined: storage.RunPubSub; Error ID: 2f5e35a0

```

The problem is ,as I noticed it, Functionbeat is requiring storage entry point. I am NOT using the gcp storage functionality, I am using pub/sub functionality with `RunPubSub`. Why is it requiring the storage entry point? I am not able to provide multiple entry points to my knowledge.

- Version: 7.13.4 ( noticed on others as well)
- Operating System: LINUX X86\_64
- Github Issue URL: [Functionbeat GCP pub/sub requiring storage entry point when only pub/sub is enabled · Issue #29967 · elastic/beats · GitHub](https://github.com/elastic/beats/issues/29967)
- Steps to Reproduce:

1. Package functionbeat using LINUX X86\_64 7.13.4 up using the following command

```auto
./functionbeat export function pubsub -c functionbeat-file.yml

```

1. Go into GCP function and go through creating a cloud function steps, upload the packaed zip,
2. **add entry point "RunPubSub"**
3. Select Golang version 1.16 in order to avoid another bug ([functionbeat 7.12 can't deploy -- unknown field 'VerifyConnection' in struct literal of type tls.Config · Issue #24925 · elastic/beats · GitHub](https://github.com/elastic/beats/issues/24925)). \<\<\< Selecting 1.13 will yield this error. Keep in mind the runtime of the function is GoLang 1.13 (could this be the problem?)

```auto
 ./functionbeat export function pubsub |grep runtime
    runtime: go113

```

My config file

```auto
functionbeat.provider.gcp.location_id: "us-central1"

functionbeat.provider.gcp.project_id: "some-project"

functionbeat.provider.gcp.storage_name: "some-bucket"

functionbeat.provider.gcp.functions:
  - name: pubsub
    enabled: true
    type: pubsub

I wonder even if I manage to get this to run if I will run into this

> Hello @Edoardo_Tenani, Thanks a lot for your advice, it worked for the deployment part. functionbeat is properly deployed on GCP cloud function with Go 1.16. Unfortunately, after sending some traffic through the cloud function I still get the panic crash error. Same behaviour as before, the first message is properly delivered to my Elastic cloud cluster. I can see it in kibana. The second message always makes functionbeat to crash FATAL [functionbeat] instance/beat.go:171 Failed due to panic.…

`Keep in mind the runtime of the function is GoLang 1.13 (could this be the problem?)`  
recompiled the functionbeat binary as goLang 1.16 and repackaged, same error.

You should avoid getting functionbeat to run on cloud function. It doesn't work and it will never reach a proper release. Edoardo told me about using a GCP dataflow template and it's working fine so far. The downside is the cost tho.

Thanks, - just surprised that they included gcp support for so long until 7.15
