Google contact sync failure

Any suggestions as to why I have started getting error messages, for all my Gmail accounts, like the following, none Gmail accounts do not produce this message:

[Google Contacts] Uploading item(s) to folder ‘[email protected]/Other Contacts’ failed due to the following error: Parameter validation failed for “resourceName” : The value did not match the regular expression ^people/[^/]+$

Thank you for any advice

I have resolved this issue, simply delete the Gmail account from em-client then add it again, you will notice that the newly added account will have a multi-coloured letter M as an icon in the list of accounts, which was not showing before, clearly showing that something is different and it totally fixes the problem. Probably equivalent to turning your computer off then on! The two accounts in the attached image without the letter M are not Gmail accounts.
