How can i fix this, a possible solution could be to use a switch to initiate the rule, but that is a workaround

[JustinG]

A very simple work around is to use a proxy item. The button can send a command to an item and the rule can trigger on the event that the item receives a command.

However, I think it’s also important to track down what’s going on here because this may impact more users than just you.

• Are you sure the rule fails to trigger (it might run but not produce the expected results when triggered remotely depending on the content of the rule)?
• Does the button work if you try to trigger some different rule while logged in through myopenhab?
• Are there any errors in the OH logs when this happens?
• Have you tried this with different browsers?
• Do you see this problem both in desktop browsers and in the mobile app?
• Do you see any errors in the browser’s console when the rule fails to run?

[rlkoshak (Rich Koshak)]

Are you logged in as an admin user in MainUI when you experience the error. The default security configuration only allows interaction with Items when not logged in or logged in as a normal user.

Open the console in the browser and show us if more information is posted there. If it’s a permission type error that’s probably the reason.

If you want this widget to work for all users, you’ll need to use an Item like Justin suggests.

Are you sure the rule fails to trigger (it might run but not produce the expected results when triggered remotely depending on the content of the rule)?
Yes, tested with a very simple rule and got the same result. Locally it works fine, via myopenhab i get the error.
Does the button work if you try to trigger some different rule while logged in through myopenhab?
No, get the same resullt.
Are there any errors in the OH logs when this happens?
Yes this is the eror

Have you tried this with different browsers?
I have tested with firefox, chrome & edge
Do you see this problem both in desktop browsers and in the mobile app?
Yes, same issue occurs also in the mobile app. Works when im connected locally, doesn’t work if remote url is used
Do you see any errors in the browser’s console when the rule fails to run?
Yes,

Im running on openHAB 3.0.2 release build.

I have the problem when i’m not logged in and if i’m logged in as admin

@akoode

415 Unsupported Media Type

In that case, your issue appears to be similar to an issue that has already been resolved:

415 error while trying to execute a rule manually

@akoode

Im running on openHAB 3.0.2 release build.

It looks like you need to upgrade your OH to get the fix, or just use the workaround.

[akoode]

Thanks, upgrade fixed the issue
