The error occurs during the layout matching in FlexiLayout Studio:
In FlexiLayout Studio it is possible to configure the database search for the Static Text element. It is possible to search in FlexiCapture Data Sets, which has the FCDOT file extension. The FCDOT file is a part of the project. If for example you are using FlexiLayout Studio from FlexiCapture 12 Release 4 Update 2, but the FlexiCapture project version is Release 4 Update 1, the above error will occur.
Update the FlexiCapture project. To do this, open the FlexiCapture project in the Project Setup Station of the same version as FlexiLayout Studio.
