I have a terraform datasource:

data "external" src {
  program = ["bash", "my_script.sh"]
}

In the my_script.sh I assert that environment variable SOME_ENV is set and if so, the script does some logic:

#!/bin/bash

if [ -z $SOME_ENV ]; then
  echo "Env SOME_ENV is missed"
  exit 1
fi

# do some work...

Otherwise, I want to highlight during the terraform apply that env is missed.

Current behaviour:
The following message is printed to the console:

...

│ The data source received an unexpected error while attempting to execute the program.
│ 
│ The program was executed, however it returned no additional error messaging.
│ 
│ Program: /bin/bash
│ State: exit status 1

Is there any options to pass error message while applying?

Thanks
