Issue with Schema in Text Area (CKANext-Validation)

[younessmalhouni]

CKAN version 2.9

Describe the bug

I'm using ckanext-validation for data validation. Uploading a schema via file or URL works, but manually entering it in the text area doesn’t attach the schema to the resource. Validation options are applied correctly, but the schema is missing.
Has anyone encountered this or know a solution?

I don't have easy access to a CKAN 2.9 instance anymore, sorry.
