Inspect your URL along with the query string using View Results Tree listener, the error can have only one reason: you're sending a character which requires URL encoding as it is.
The reasons are in:
One of your variables (${location}, ${prodName} or ${authToken}) has the character which requires the URL encoding. If this is the case - you will need to wrap it into __urlencode() function
One of your Variables (${location}, ${prodName} or ${authToken}) is not getting resolved into the value and curly braces characters ({ and }) are not allowed in the URL string without encoding. Use Debug Sampler to make sure that :
all the variables have their values
all the characters which require the encoding are encoded using the __urlencode() function
