Attempt to decode JSON with unexpected mimetype

I’m getting this error while trying to use an RGBW LED controller (note: I replaced the full access token with xxxx)

I brought up the URL from the error and this is the output:

I've suddenly started getting this error too when changing the levels of bulbs. Actual control of the bulbs still works fine. The error just pops up at the bottom of my dashboard when I change the level on any of them. I wonder if a Hubitat firmware update might be the culprit.

I've seen that error sporadically for quite some time. I'd guess in those cases that Hubitat is sending back an HTML error page rather than the expected JSON data. It's such a sporadic error that I've never really looked much into it. I really need to add some debugging code to see what Hubitat is actually returning on those cases...

I’ve been experiencing it for a while, going back at least several versions of the Hubitat firmware. I just finally got around to trying to see if I can get it resolved. But definitely looking like it’s a Hubitat issue.

Good to know it’s not just me. Maybe I’ll see if I add some debug code and reproduce it. At least then a bug can be raised with Hubitat.

For me at least, this was fixed in v0.9.11 :)
