I have a report in SQL Server Reporting Services in integrated mode (baked in to SharePoint) which has a multi choice dropdown that can have more than 1000 values. The report works as expected in IE 11 but in Chrome (latest version at this point) I get:
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 413
This occurs when the dropdown is filled and the user selects all or some values and then closes the dropdown. It is intermittent so it does not always happen.
In our test environment, that is not in integrated mode, the report works in both in IE and Chrome.
For SharePoint we have reviewed the settings and all settings is in default. for example maxReceivedMessageSize = ‘115343360’
, which would be enough I think. If Im not wrong, say the average character count in the dropdown is 15 and we have 1200 values. That would be about 36 MB of data to send to the server if assuming UTF (2 bytes) is used.
