#9971 fix(cli): Improve `meltano config test` error message with helpful hint Pull request opened by Sharanjoo Summary Improves the error message shown when

meltano config <plugin> test

fails by adding a helpful hint for users. Problem Currently, when plugin configuration validation fails, the CLI shows a generic message: "Plugin configuration is invalid" This can make it harder for users to understand how to fix the issue. Solution • Added an additional hint suggesting users check plugin settings in

meltano.yml

or environment variables • Preserved existing behavior and output structure Changes • Updated error message in

src/meltano/cli/config.py

• Added a new regression test to verify improved error output Testing • Added unit test:

test_config_test_invalid_shows_hint

• Verified test passes locally using pytest Impact Improves developer experience when debugging pipeline configuration issues.

meltano config <plugin> test

error message when plugin configuration validation fails. Tests: • Add a regression test to ensure the updated invalid configuration error message and hint are emitted as expected. meltano/meltano
