Unexpected error doing ModifyCloudGDReg (Kubuntu)

I have entirely done a vanilla sync because I have dozens of error messages. Now I only have one with this supplement information (insufficientPermissions to perform this operation). But no information is available to know what operation is concerned.
Kubuntu 18.04.03

Can you send in the screenshot of the error message as well as the logs to support@insynchq.com?
