Description

Wanted to setup http send report. The url is http(s) URL and using POST method. The message needs to be send in POST body. The sent http function was triggered but return warning that there is illegal path character. It seems like the message is sent thru URL parameter instead of post body. I cannot find option to set the message into POST body. Not sure if this is supported.

Steps to reproduce

1. Set "send-http-url" to "https://api.domain.com/network"
2. Set "send-http-message" to "{"DisplayName":"Duplicati Backup Monitor", "Subject":"Duplicati %OPERATIONNAME% report for %backup-name%","Body":"%backup-name%"}"
3. Trigger backup and wait for completion
4. Backup successful but return warning on illegal path detected error.

• Actual result:
  Backup successful but return warning on illegal path detected error
• Expected result:
  Backup successful and https post request sent with the message in post body

Debug log

Due to the system was setup by Asia region IT support, the error is in chinese characters. The translation of it using google translate is "Illegal characters in path"

The message is sent with POST.

The --send-http-message parameter is a bit confusing, but is used to specify what fields are included in the message.
The implementation of a custom message is broken in this case, because it checks if the message is a filename here, and the template-like string you supply is not a valid path. This should be fixed.

You can place the text in a file, and then set --send-http-message=path-to-file.

But it looks like you want to send JSON data, so perhaps it is easier to remove the --send-http-message parameter and set --send-http-format=json ? This also correctly handles cases where the text contains characters that needs JSON escaping.
