IFTTT humidity trigger no longer working

I have a IFTTT recipe that turns a humidifier off and on depending on the humidity level. It was working fine yesterday when I set it up and now it appears to not be triggering. When I look at the humidity value in graph.api.smartthings, I see it at 42%, below the value it should be triggering at. Yet no matter how many times I tell IFTTT to check the value, it doesn’t turn on like it was yesterday. I tried the humidifier smartapp in the market and it wasn’t working correctly either.

I noticed on the logs for IFTTT on the smartthings api site I saw several lines of:
Error parsing ifttt payload groovyx.net.http.ResponseParseException
