Ignore non-existing datasource

[ghost]

Hello,

We are trying to generate providers and resources list for Terraform based on two sources concatenation

1. CI defined variable
2. AWS Secrets Manager secret

AWS SM secret is created by this Terraform code and it means that at the initial run secret doesn't exist yet and execution fails:

gomplate -f main.tf -o - -d secrets_regions=aws+sm:secrets_regions

20:36:18 ERR error="failed to render template main.tf: template: main.tf:13:53: executing "main.tf" at <ds "secrets_regions">: error calling ds: Couldn't read datasource 'secrets_regions': reading aws+sm source "secrets_regions": ResourceNotFoundException: Secrets Manager can't find the specified secret."

Is there a way to ignore the error of non-existing datasource?

Hi @air3ijai, thanks for taking the time to post this.

(FYI I edited your post to fix a broken link to #1168)

I think what you're looking for is the datasourceReachable function, which is designed for this type of situation.

Another option is to use datasourceExists, and simply not specify the secrets_regions datasource on the first run (if you know the value won't exist).

See the docs for examples on how to use these in an if/else block.
