 ### Features
 
 ### Fixes
+* **Fix passing parameters to python-client** - Remove parsing list arguments to strings in passing arguments to python-client in Ingest workflow and `partition_via_api`
 
 **table metric bug fix** get_element_level_alignment()now will find all the matched indices in predicted table data instead of only returning the first match in the case of multiple matches for the same gt string.
