Hi @21f3001806 , I recently got a similar error for my old pipelines. so databricks recently made dlt direct publising mode ga which caused some changes in the dlt pipeline configuration definition so if you use the setting 'target' in your pipeline it will show legacy , if you change it to 'schema' it will be corrected. Basically it means that dlt supporting unity catalog.

here's the link : https://www.databricks.com/blog/publish-multiple-catalogs-and-schemas-single-dlt-pipeline

Not sure whether this is the right solution but you can give it a try
