Platform, CI, or deployment failures

Environment, dependency, or configuration mismatches between WGU lab, local student setups, and assessor environments causing runtime errors or failures

• My project runs flawlessly in the lab ... But I got a rejection saying the code doesn't even compile ... it appears the code doesn't run on local machines ... Something to do with SQL database not connecting? ... I don't know if I need to change the credentials for the SQL or what....

• [I'm getting the exception called "ExpressionChangedAfterItHasBeenChechedError" on page load. This error is not present when running the front end from vscode. Everything I'm seeing online about this error implies it is due to an issue in the front end (which we're apparently not supposed to edit). If this is an error with the provided code, can we safely ignore it?]
