Getting errors deleting documents from collection related with another
Simplified Setup:
3 related collections
- Color (attrb: name)
- Shape (attrib: name, shapeColor[related field])
- ShapeColor (attrib: color[FK: m-to-1 on Color on delete set null], shape[FK: m-to-1 on Shap on delete cascade]
Deleting a document from Color doesn't set the related fields in ShapeColor to null but throws an Server error. Appwrite container logs

Summary
There are errors when deleting documents with relationships. Deleting a document from the 'Color' collection doesn't set the related fields in 'ShapeColor' to null and throws a server error. On the other hand, deleting a document from 'ShapeColor' throws a 'Document not found' exception. No solution is provided in the support thread.
