Using JMeter __FileToString function, getting java.io.FileNotFoundException

I am using JMeter __FileToString function to read JSON file in the request body as below.

${__FileToString(C:\\Users\\prasad\\Office\\SSP\\16.48\\sprint3\\${__eval(${CSV_Challenges_Dataset})}.txt,,)}

but I am getting below error when I run test. Can someone point me to right example on how to use JMeter fileToString function in windows.

If CSV_Challenges_Dataset is a filename, In that case, you can directly access it as follows:

${__FileToString(C:\\Users\\prasad\\Office\\SSP\\16.48\\sprint3\\CSV_Challenges_Dataset.txt,,)}

Don't include it in eval method if CSV_Challenges_Dataset is the actual file name.

If CSV_Challenges_Dataset is a variable, then you either you have NOT defined (Set the value) it in JMeter Test Plan. From logs It is clear that you do not define the value CSV_Challenges_Dataset.

 Could not read file: C:\Users\prasad\Office\SSP\16.48\sprint3\${CSV_Challenges_Dataset}.txt File

If defined, CSV_Challenges_Dataset should have been replaced by the actual value.

Add Debug sampler and View Results Tree, to know the value of CSV_Challenges_Dataset during run-time.

Most probably this is due to your ${CSV_Challenges_Dataset} variable is not set. Add Debug Sampler somewhere before this function and double check that the variable value is set and it resolves to file name. You can view JMeter Variables names and values using View Results Tree listener. See How to Debug your Apache JMeter Script article for details on getting to the bottom of your JMeter test script failures.

Just in case, you don't need to wrap your ${CSV_Challenges_Dataset} variable into __eval() function, __FileToString() function is smart enough to resolve the variable.
