An unexpected client error has occurred

(1) ShareShare
ReportReport
Posted on by Teach 3
Recently users are frequently getting this error pop up when navigating to numerous screens in Finance & Operations (10.0.34). The error does not appear to impact functionality if you close it, however, is very frustrating for users as can pop up 100's of times a day.
 
There is no custom development, just vanilla F&O deployment.
 
The error does NOT occur if Firefox is used as the browser, only in Microsoft Edge/Chrome. However, our corporate SOE browser is Microsoft Edge so this workaround is not practical on a large scale. 
 
Issue has started in the last week only.

    @Stuart Bird: It is related! I've had this issue for months now. Nothing of the answers I have found elsewhere actually helped. I added the dynamics.com to the never list in LastPass to prevent automatic fill in and it worked!! This was a real saver!

    It maybe unrelated, but I had this issue and it was due to LassPass trying to populate various fields, added the dynamics.com url to the never list and the issue went away,

    We are getting this constantly. Resetting the usage data is not correcting the issue for us either. I reset my usage data and then received the error on the usage data screen immediately after. Anyone know if Microsoft is working on it?

    Have since moved to 10.0.35 but the issue remains.
    Clearing user data, and browser cache does not resolve.
    Firefox works fine. Only Chromium based browsers through the error. 
     
    I think a recent update for Edge is causing the issue. Hopefully MS can move quickly to resolve!

    Hi Teach,
    The same problem as yours is mentioned in the link below, you can refer to the method in the article:
    Unexpected client side errors keep popping up in D365 Finance & Operations - Help / Activities - UiPath Community Forum
    Or you can try to clear your browser cache and try again.
    Best Regards,
    Hana

    If it's in T2+ environments only, look into logs in LCS. If you can reproduce in T1 boxes too, look directly to event logs.
