I’m new to Duplicati. Running the docker image and trying to setup an backup of my home assistant directory. When I run it, it fails with Character is not a Base32 character.Parameter name: c. Some sort of encoding issue? Not sure what it means in this context.
Clicking “Show” does not reveal any logs. I have taken a log dump but I could not see anything obvious in the database.
There should be a more detailed message in the Server log, in the About section.
Aha, this is what it says:
System.ArgumentException: Character is not a Base32 character.
Parameter name: c

The stack trace is not really helping unfortunately. Is there anything else in the server log? You can also run it with the live log open at verbose level to get more log output. This is probably an invalid character in a path or in the configuration. Can you post the job configuration (without personal info)?
I thought as much. 
Which log do you refer to more exactly?
Sure the configuration is pretty straight forward. I noticed there is an export option of the job. It looks like this:

}
}
On the server log, there is a second tab (live). You can keep that open while running the job and it will show more messages if you set it to verbose.
Does your exported target URL contain any characters that are not valid for URLs (e.g. spaces) and should be encoded? Sometimes the UI does not do that properly
Alright, checked the live log now with verbose setting and triggering a job. Sadly, it is still a cryptic stack trace:

My target folder path is just a name, no backslahes or anything like that.
Huh! I just clicked test connect and I got the same error!
Maybe it does not like my password? But I did try the test connection when I first created the job and it worked fine.
Edit: I just changed to google drive and now it seems to work just fine. I guess the Mega integration is buggy.
