No cross-scope access policy exists between the source application and target application scope to allow the requested operation. (high likelihood)
The cross-scope access policy exists but is configured with incorrect operation types or does not include the specific table, Script Include, or API being accessed. (high likelihood)
The cross-scope access policy is inactive or has been disabled, preventing the scope access even though the policy configuration appears correct. (medium likelihood)
The script is running in a different scope context than expected, such as when called from a different application or when scope inheritance is not working as anticipated. (medium likelihood)
The target resource has been moved to a different application scope since the original cross-scope access was configured, breaking the existing access policy. (low likelihood)
