Apologies for the late response! This form of error used to be emitted whenever the Accessibility Insights for Azure DevOps task encountered a browser error during a scan. It wasn't very actionable, and it was improved as part of resolving issue #1315. Whatever underlying browser issue was causing the error for you should be explained more clearly in error output nowadays.
If someone viewing this question today is still seeing an error like this (specifically, containing the line caused by: TypeError: Cannot read properties of undefined (reading 'baseUrl')), double check that you're using the latest version of the task (as of writing, @3).
