3. See error

Between string function
Returns substring from start position to end position [,003 sec] (FAILED - 1)

2. zero_start_position
   Call params for test are not valid: package does not exist or is invalid: SCHEMA.TEST_BETWNSTR
3. big_end_position

Expected behavior
Should be successfully run as in another schema in the same database.

Example code
betwnstr/test_betweenstr packages from demo project

Additional context
Maybe this is grant / object related (eg. duplicate system views in the schema or similar)
