Variable name that is not valid

The check compat/variable-name, in the group Engine compatibility.

Error

Why it matters

A name that starts with a digit or holds a space or a dash cannot be used in a FEEL expression, so it can never be read again.

How to fix it

Use a name of letters, digits and underscores that does not start with a digit.

Where you see it

The Problems tab lists it under Engine, the editor marks the element on the canvas, and penstock check reports it as compat/variable-name. It checks the diagram against the engine and the version it is written for: the version in the file's modeler:executionPlatformVersion, or the newest one when the file has none. Operaton and CIB seven are checked as Camunda 7. This check is free.

To turn it off, set camunda-compat/variable-name or compat/variable-name to off in your .bpmnlintrc. See Validation.
