Sorry but I have not received it, can you resend?
While at it please address my comment below.

This sentence doesn't read well. Please adjust it a bit to make
coherent sense, and resend it.

Perhaps you can use something like this:

We already issue a custom firmware debug print message when no file / path
was not found, however only the error code is returned. Stating clearly
that the file was not found is much more useful for debugging, so let's
be explicit about that.
