Failure issue with google deployment manager CLI

[AThakur812001]

Can anyone please help me fixing the issue I am getting while deploying-cloud functions-v2 through deployment manager CLI.
When I am running gcloud deployment-manager create deployment --config it is performing its action and executing the command to success sometimes but during times it is getting failed with error message.

Error in Operation [operation-1705053461174-60ebcb1e0598c-a36b0537-bb184b9f]: errors:
- code: RESOURCE_ERROR
  location: /deployments/my-first-deployment/resources/first-manager-stack
  message: "{\"ResourceType\":\"gcp-types/cloudfunctions-v2beta:projects.locations.functions\"\
    ,\"ResourceErrorCode\":\"400\",\"ResourceErrorMessage\":\"Could not create or\
    \ update Cloud Run service first-function, Container Healthcheck failed. Revision\
    \ 'first-function-00001-suv' is not ready and cannot serve traffic. The user-provided\

    \ \\nFor more troubleshooting guidance, see https://cloud.google.com/run/docs/troubleshooting#container-failed-to-start\"\
    }"

I have tried various different methods , gcloud flag for async but still no help.
Can some help me out in this.
Also let me know what is the default timeout for deployment manager and is there any way to change it?
Because I tried referencing various docs and official pages of GCP but got no help.
