When navigating to the Export License Connection window and selecting the Search option, the following server error occurs:
“ExportLicenseConnections/LicenseConnectionsPage (server error) – Error while serializing contents.”

During further investigation, it was identified that the issue is caused by the ‘Export License ID’ field. An attempt was made to modify the field length using the Page Designer; however, the same server error reoccurs when clicking on Search.

Below is the server error information.

ExportLicenseConnections/LicenseConnectionsPage (server error)
Error while serializing contents.

This error happens when the server cannot serialize the data to be sent to the client.
A common cause is that one attribute's length exceeds the defined maxlength in the projection.
To find more info, open Log Window or Debug Console, refresh and then check Network Tab in DevTools. In the response there can be more detailed information about the exception.”
