Unexpected error during process_event

Third party integrations AppDaemon
1

Hi - please can someone help me diagnose where/how this error is occurring in my AD setup? I’m getting rather a lot of these errors and I can’t work out what is causing them as there doesn’t seem to be any references to my code in the error message. Does anyone know how I can find out which app is causing this error to happen? Thanks!

I’m running version 4.03 using the docker image.

Do you have some automations which use now_is_between?

Hi Burningstone, no I don’t have code anywhere.

Any app with time constraints?

5

Yes I’ve got quite a few of those, e.g.

constrain_start_time: 16:00:00
constrain_end_time: 22:00:00

I’ve just noticed they are not in quotes - is this the problem?

This might be a problem, I’m not sure. Try to put them all in quotes and see if the error disappears.

I’m going to do that - thanks for the suggestion.

I have used the time constraint in a few apps and just checked, this was the only one without the time encapsulated in quotes. Coincidentally it was one of my first apps I wrote and I had forgotten all about it. Looking at it now, I know the app has not been running. If that’s the case then that one app has been kicking out a lot of error messages in the log! I’ll report back here and update later if this has fixed the problem. Thanks again.
