In a recent project I receive the following error during Sonar analysis from a PR:

Corresponding code is

catch (Exception ex)

which I assume throws a CA1031 error.

Any idea what might be causing this?

Btw the file where the error occurs was added in the PR

Full log from the VSTS run available here.

Thanks @pascalberger, will investigate. Is this an ASP core project or an older flavour of ASP?

@bgavrilMS Worse, a SharePoint full trust solution :)

Hi @pascalberger - apologies for the long delay. We're actually looking into simplifying the implementation of PRCA as it uses some APIs that are too low level. Long story short - I have no idea why that assertion is thrown. All the files in the CR should have changes... . We'll try to repro the problem to find out more.

In the interim, consider commenting the assertion out:

[bgavrilMS]

Short term fix - ignore the messages if the underlying file changes are not found. In the longer term, we're looking at using a higher level API that should shield us from this.
