This error is caused by data on the LRBG application being either missing or in the wrong format. If you are unable to see any issues after reviewing this then it is possible to enable some debugging to get further information:
Sign in to Proclaim and open System Parameter Maintenance.
Find and select the WebServices Debug system parameter.
Click UPDATE and set the value to Yes, click SAVE, minimise System Parameter Maintenance.
Open Main Case Handling/Proclaim Desktop and open the case in question.
Open the Enquiry page and click the LRBG eDRS Application screen.
Click UPDATE and click Send Application to LRBG.
Click YES then YES then NO, the error will then be produced.
Open System Parameter Maintenance and change the WebServices Debug value to No.
Open Windows File Explorer and type %temp% into the file path bar, open the Proclaim folder.
Right-click the XML file that ends in -Error and open using Internet Explorer.
Use this document to deduce the cause of the error.
E.g: The value " of element 'PostcodeOfProperty' is not valid would mean that the PostcodeOfProperty text field is blank and is causing a problem. Any field flagged with '.*\S' means some data that needs to be on a single line has gone over two or more, this could be due to a carriage return being added at the end accidentally if the information was copy/pasted in.
If you need further assistance with this issue then please raise a new case online and reference the title of this article and, if possible, supply the debug files created via the steps above.
