I am getting and invalid syncToken when performing and ISync on the message store after running the FSync to get a token. The FSync works fine but when I use the returned token to follow up with an ISync I get the error. I can also replicate the problem by just using the api interface at https://developers.ringcentral.com/api-reference/Message-Store/syncMessages. If I run an FSync and then copy the returned token into the form field and switch to ISync I get this error:
{ "errorCode": "InvalidParameter", "message": "Parameter [syncToken] is invalid", "errors": [ { "errorCode": "MSG-333", "message": "Parameter [syncToken] is invalid", "parameterName": "syncToken" } ], "parameterName": "syncToken" }
