Question

Which workflow command would set the debug message to This is an error message?

A. echo “::error::This is an error message”
B. echo “error=This is an error message”
C. echo “::error::message=This is an error message”
D. echo “::error::This is an error message::”

Answer

A. echo “::error::This is an error message”

Explanation

This syntax is correct for this workflow command.

The correct workflow command to set the debug message to “This is an error message” is:

echo "::error::This is an error message"

This uses the special GitHub Actions workflow command syntax to set an error debug message. The syntax is:

::error::<message>

where <message> is the debug message you want to set.

The other options are incorrect:

  • Option B uses the wrong syntax of error=<message>
  • Option C incorrectly tries to use message=<message> in addition to ::error::
  • Option D has an extra :: after the message which is invalid.

So in summary, to properly set a debug error message in a GitHub Actions workflow, use:
echo “::error::<your message here>”

This is the accurate and expected syntax for setting debug messages in GitHub Actions workflows.
