SyntaxError: Unexpected token '?' when action is executed

[jnsvd]

How would you describe the issue?

An error occurs when auto-merge is attempted since v2.9.31 (and the corresponding bump of the v2 tag).

How can we reproduce the issue?

Push a new commit that leads to an action execution with an auto-merge step.

What are the expected results?

Auto-merge being executed.

What are the actual results?

The following error is observed:

How much does it hurt?

We can specify the previous working version 2.9.30 to be used, but tag v2 is currently not working for us.
