The error message 'Unable to create a build on the specified database and schema' points directly to insufficient privileges for creating the model build itself. While the database role enables working on Document AI models and using SQL for extraction, specific object privileges are required to create the model 'build' in a given schema. The documentation explicitly states that 'CREATE SNOWFLAKE.ML.DOCUMENT_INTELLIGENCE on the schema is required to create model builds (instances of the 'DOCUMENT INTELLIGENCE' class), along with 'CREATE MODEL' on the schema. Option A (USAGE on database) is a general prerequisite but not the direct cause of this specific 'unable to create a build' error. Option B CCREATE TABLE) is for creating tables, not model builds. Option D (s EXECUTE TASK) is required for running tasks in a pipeline, not for model build creation. Option E is incorrect as warehouse size primarily impacts cost and performance, not the ability to create a model build due to privileges.
