Failure issue with google deployment manager CLI

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:

}"
```
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.**
