Attachment Upload Failed - 3cx Chat, Android, IOS, Web browser

[Digital Genius]

We rolled out 3cx to a customer and all is fine apart from the chat - they have been sending photos and one by one the users have got the below message. Once this is error is received the user cannot upload a photo from any platform. These images stay in the chat as uploading with the spinner.

Exception of type System.NullReferenceException occured in 'SendChatMessage' line 5023. Message: Object reference not set to an instance of an object

The only reference I can find to this is on the German Forum from a week ago with no response. All platform list the exact same message.


Can someone help where to start diagnosing this. I can see from chrome the exception is returned in the POST request to /MyPhone/MPWebService.asmx

Restarting the 3cx Management Console Service allows these users to send images again, the failed uploads change from a spinner to a cross.

There is obviously and issue here with failed uploads
