Multiple path params not working

Hi Folks, Recently I have encountered an issue where I have two path parameters for an api endpoint where both are mandatory, but when we execute the api via swagger and pass the value for them, for 1st param its fetching fine but for 2nd one its returning the name of the paramater. Below are the details.

For Example:

I have passed 2 values for 2 fields named as budget_name and partition_name as budget1 and partition1

but when I logged(print) them, I got budget1 [which is correct] and {partition1} [not correct its treating field name as value].
