EXP-00090: cannot pin type "string "."string "
What triggered the Error:
Export was unable to pin the specified type in the object cache. This is typically caused because a type could not be made valid (for example because of authorization violations in accessing subtypes).What should we do to fix it:
Fix the problem with the offending type until the type can be successfully compiled.
