Error in executing a smartobject
 

Diagnoses

We're getting this error when executing a smartobject:

10702 An error occurred in the Tracking_webservices service instance. There was an exception running the extensions specified in the config file. ---> Maximum request length exceeded.

The smartobject here does not communicate with databases or anything, it simply receives XML text and return it in Base64 String.
We're also getting the same error when trying to open some infopath forms from the worklist.

P.S. we haven't changed anything recently in any config files.

 

Resolution

Issue was with the web services configuration of maxRequestLength attribute

from the error it seems that there is a limitation in the size if the info that is sent to this webservice. i think you will need to adjust the

maxRequestLength setting in the web.config


Please note that The maximum value that you can specify is: “2097151”
