Error - Unable to replace parameters.

Hi All!

 

I having trying to customize a request substituting  a parameter in  a JSON body request. I have been trying to use csv file, excel file, even a static variable. I continue receiving the below message: 

 

Unable to replace parameters. Error: Unable to change the parameter value,
because the variable value cannot be converted to a value of the parameter's type.

To solve the problem, use the appropriate data type and value for the variable.

Parameter: [Unnamed]\variable

 

 

This make me thing that the problem could be the replacement itself, like a string is been used rather than a number. Nevertheless, I am using numbers. Not sure if there is something else I am missing.

 

Any help will be appreciated.

 

Regards

    Hi,

     

    Not sure what exactly you are trying to do... Can you provide some screenshot(s) illustrating what you are trying to replace and with what? Considering message text, I would guess that some string value that cannot be converted to an integer is used.

      Hi Alex

       

      The parameter indeed is a numeric value. I tried to substitute using the above options without luck. For my understanding, this should be a pretty straight forward parameterization. However, the tools is failing in doing it.

       

      The parameter to be substituted is "ScanCode". It's using a number like this:

      The variable I have tried to substitute using:

      *  Static variable 

      * A entry from CSV file. The content of the file are the same type of values (80000000000X where X is a number).

      * Even just substituting the last 4 characters in order to avoid a length issue (just substituting 0002 ).

       

      Always, I get the same error:

       

      I guess the trouble is that the parameter is marked as "number" and cannot accept a string. However, I don't see a way to change that.
