Cause

The LevelLayoutGuidLookup error could be caused by an invalid database condition where a Sub-Form does not have a layout. The following SQL query can be used to look for Sub-Form modules that do not have a layout.

/*  Find sub-forms with no layout */
SELECT 
	mt.module_name
,	mtype.module_type_desc
,	lm.layout_module_id
,	lm.layout_module_name
FROM tblModule m 
FULL JOIN tblIVLayoutModule lm  on m.module_id=lm.module_id
JOIN tblModuleTranslation MT on m.module_id=mt.module_id
JOIN tblModuleType mtype on m.module_type_id=mtype.module_type_id
WHERE m.module_type_id=5 
AND MT.is_default=1
AND lm.layout_module_id IS NULL
ORDER BY mt.module_name

 

Resolution

Delete the corrupted Sub-Form from the Application Builder.
