When uploading to a notion database a TEXT field that is over 2000 characters the upload fails and the following error is given. Note both the flush functions are also not working.

could not flush the insert buffer. Run SELECT flush_buffers(tableName) to retry the query. Or run SELECT clear_buffers(tableName) to clear the buffers (data loss). Err: could not insert the rows in the plugin
body failed validation: body.properties.myField.rich_text[0].text.content.length should be ≤ 2000, instead was 2500.

notion fields may be typed in for more than 2000 characters so I am not sure where this limit is coming from.
