Error passing Sting input into Python script

I am trying to pass a string variable I got from Input Dialog into a Python function as an argument. But when I tried to put the variable into Input Parameters, I get the error below:

String’ cannot be converted to ‘System.Collections.Generic.IEnumerable(Of Object)’ because ‘Char’ is not derived from ‘Object’, as required for the ‘Out’ generic parameter ‘T’ in ‘Interface IEnumerable(Of Out T)’.

Can anyone help please?

Hi @Toby_T

Pass the input arguments like this

{Your_input_variable}

Thanks

Hi Robin, thanks, it worked. Now, I changed my function to take in both a string variable jsonInput and a double variable as an argument but I got this error in the logs:

Hi, please find below:

This are my arguments:

I can’t share my expected output but it is a dictionary.

I also added this below in my code, if it helps:
