This wasn't the case on pre 1.5.x if I am not wrong.
We should probably use an empty string as a default as one is already used during executions, see here.

I am open to contributing to this if assigned.

👍 Expected behavior

Process the deployment like the previous versions, assuming index.js as the default entrypoint.

👎 Actual Behavior

Server Error.
