x-ms-docs-grouped-path:
- '/drives/{drive-id}/items/{driveItem-id}/delta(token=''{token}'')'
- '/drives/{drive-id}/items/{driveItem-id}/workbook/functions/delta'
- '/drives/{drive-id}/list/items/delta()'
- '/drives/{drive-id}/list/items/delta(token=''{token}'')'

The x-ms-docs-grouped-path /drives/{drive-id}/items/{driveItem-id}/workbook/functions/delta should not be there, because it's an endpoint for workbook function to test whether two numbers are equal.

Start by locating the beta OpenAPI document generation inputs and transforms, then search for the exact x-ms-docs-grouped-path entry and the workbook delta endpoint. Remove the unrelated grouped path from the generated metadata and regenerate or validate the beta document to confirm the remaining paths are correct.
