We have built the workflow and want to publish on the share point, using the share point output tool, But the flow is getting failed with the below error ::

"str object has no attribute get"

and also when i select all the fields it throwing an above error, But when i have selected few fields it running without any issue.

Kindly help me out this and I'm using share point output tool 2.5 and designer version 23.1.
