Improve Cron Trigger Validation Error Message

[korenyoni]

When the cron expression is not valid, it will fail to apply the plan with a generic error message

unexpected end of JSON input

Trying to add a trigger with an invalid expression:

Terraform will perform the following actions:

  # codefresh_pipeline_cron_trigger.test will be created
  + resource "codefresh_pipeline_cron_trigger" "test" {
      + expression  = "*/1 * * * test"
      + id          = (known after apply)
      + message     = "Example Cron Trigger"
      + pipeline_id = "638dd23ef1882a1825e515d8"
    }
Plan: 1 to add, 0 to change, 0 to destroy.

Result:

codefresh_pipeline_cron_trigger.test: Creating...
