This task explains how to troubleshoot problems in Experience Manager that you see when trying to update preview.
Procedure
- Check for the following error in the Preview Service logs:
ODataWebHandler - Validation exception while updating an entity.
com.sdl.web.content.odata.exceptions.ODataValidationException:
The input data was invalid:
stringValue must be a non-empty string or any of the other values should be filled in.
- If you see this error, check if the URL for which you are trying to do an update preview matches an excluded path in the
ExcludedPaths section of the cd_ambient_conf.xml configuration file. If the URL matches one of the paths configured there, filtering is excluded for this URL, which is why update preview does not work.
