Description

I went into the settings for my mqtt integration and changed message format to csv for a second. When switching back, I got the aforementioned error message, even though there is nothing else in the form.
See screenshot:

It also says "Connection options" must be object, but its empty?!

Expected Behavior

I should be able to switch between csv and json and not need to supply connection options if its not necessary.

Steps to reproduce

1. Go to mqtt integration settings
2. Change message format to "csv" and hit save
3. Change message format back to json and hit save

Actual: See screenshot above

Environment

Fedora 43, Firefox 148.0.2
Fedora 43, Chromium 146

Console Output

Workaround

None. Actually when trying to disable the integration, I get the "Connection options must be object" error.
