Cursor Pagination Broken

Hii, i am facing an error with cursor pagination where i get this error when i use the cursor to paginate through the after and before fields
cursor invalid: filter invalid: column [character-\u003eelement]: invalid identifier, column [character-\u003eelement]: invalid identifier, offset 10: invalid symbol [\], only alphanumerics and '-', '_', or '~' are allowed
cursor invalid: filter invalid: column [character-\u003eelement]: invalid identifier, column [character-\u003eelement]: invalid identifier, offset 10: invalid symbol [\], only alphanumerics and '-', '_', or '~' are allowed
this happens when i use filter on JSON nested key character->element

Hi, indeed there is a bug with paginating queries with json filters. We added an internal issue and will follow up. As development is currently focused on Postgres compatibility and features rather than the REST API, I cannot provide an estimate for fixing the issue. As a workaround you can use SQL https://xata.io/docs/sdk/sql/overview with the xata.sql call in the SDK and paginate with OFFSET/LIMIT.
SELECT * FROM "tablename" WHERE (character->>'element') = 'value1' OFFSET 20 LIMIT 20;
SELECT * FROM "tablename" WHERE (character->>'element') = 'value1' OFFSET 20 LIMIT 20;

The SQL tab in the docs here provides an example statement as well : https://xata.io/docs/sdk/filtering#working-with-json-documents
Filtering records
Use the Xata SDK to filter across APIs for versatile functionality

Ohh I can implement a workaround no worries, I'd rather not change complete pagination Just wanted to report this

The reason I am in constant denial of using raw SQL query is because I love xata's cursor pagination, on subsequent calls to getPaginated passing cursor retrieves all the filters and sorting from initial query Makes it a breeze to paginate through Hii, I know this is not a priority but could someone from the team just send a message in this thread this whenever this is fixed? Thank you!

Certainly, we've linked this thread to the internal issue so once that is addressed we will drop a note here 👍
