Pb with send-http module (solved)

installed : Duplicati - on the date of release.

Error msg:
Warning while running xxxxx
2024-05-16 13:10:35 +02 - [Warning-Duplicati.Library.Modules.Builtin.ReportHelper-ReportSubmitError]: Échec de l’envoi du message: System.ArgumentException: Illegales Zeichen im Pfad. ArgumentException: Illegales Zeichen im Pfad.

That is: Illegal characters in path.
Note that only the reporting to duplicati-monitoring.com failed, not the backup itself.
All send-http parameters were unchanged with respect to previous Duplicati release.

Only one backup reporting has this issue → look for differences in send-http params.
Change send-http-url → bug remains.

Eventually I reverted send-http-message to default by clicking the cross in the “Options” and the problem was gone. I did not take note of what it was when the bug happened.

Hope this can help someone.

That sounds a lot like this error:

It happens when supplying a value for --send-http-message.
This can either be a template string or a template file.
If it is a template string, the checker will fail when trying to determine if it is actually a file path.

Right. It is the same bug. I wonder a bit why it was not a bug in the previous Duplicati release though, but you can fix it easily so let’s leave with it.
