I'm working on creating a custom connector for Microsoft Teams. I've created one based on the github tutorial repo. Everything is working fine but when I hit the save button nothing happens, seems like saveEvent.notifySuccess() is not working. I'm using React for the config page.

Any help will be appreciated.

I can't find the error. I've been trying for a couple of days to solve this and trying so many things.
Please help.

Just a thought out of the blue:
You enabled external side loading in teams settings?
I didn't change it. By default, I think it's turned on.
Can it be related to that? I do not have admin access, Will check with the admin if it's turned on.
No its not turned on by default afaik
From where can I enable this?
I've looked everywhere. Can't find it.
This setting is still in the services and addins under teams, in admin portal
It's already On.
I think the problem is caused by something else.

Did you ever find out the source of your issue? I am experiencing a similar issue. Same UI error back from MS Teams when I hit save from my successfully sideloaded app. I have confirmed that my

registerOnSaveHandler()

is being invoked and that 

saveEvent.notifySuccess()

 is being called.

 

Teams is returning a 500 - this is what i see in the browser logs:
