Action aborts with: Error: Cannot read property 'split' of undefined

[rsoesemann]

When I created a PR with an Apex change the PMD Github Action aborted with this

analyze
Cannot read property 'split' of undefined

Looks like it aborted after parsing the SARIF of the second issue. At least only one is displayed correctly

We call split here:

pmd-github-action/lib/annotations.js

Line 55 in 76f6e25

const lines = rule.fullDescription.text.split(/\n|\r\n/);

I think, this problem occurs if a rule has no description... the action should however not abort, if this is the case.
