Unable to edit Sharepoint list item - Invalid date-time value
aapokwe have the same issue frequently appearing. Switching to classic mode works as a workaround but it's not really a solution as this shouldn't appear in the first place. I'm wondering if anybody has found the root cause for this? And is there a way to avoid this issue altogether?
To me this seems to relate to the fact that people might have different regional settings and in our case it started to affect us once we changed the site number format to Finnish style. It appears to me that somehow sharepoint's modern version is unable to interpret the date formats automatically.
- Juho_Risku Still haven't found a solution 1,5 years later. The only thing that has worked for me has been clearing the cookies, this fixes the issue until it pops up again.
aapokThanks. It's a bit disappointing, as this seems to be a clear bug on the Sharepoint side... hopefully someone at Microsoft end picks this up at some point.
aapok Clearing cookies works for me as well. To make it easier, I configured Edge to clear all SharePoint, Powerxxx, Office365 and msftauth related cookies on exit: Settings->Cookies and Site Permissions->Manage and Delete cookies...->Clear on Exit. This automatically resets the environment every time I quit working for the day. You will have to sort through your list of saved cookies to find the relevant URL's. The setting also supports a wildcard [*.] (braces included) at the beginning of the URL to clear everything from that domain. Example: [*.]powerautomate.com.
