Eggplant Functional apitest requestbody change full json data

I want change full json data of requestbody.
I scripted below

put JSONValue(file “c:\Temp\test.json”) into fileContents
apitestname{requestbody: fileContents}

but json not update new json data.

I checked. The script is applied as shown below

apitestname{url: “sample url”}

I need some advice…ths

I would put the text representation of the JSON file content instead of an SenseTalk object to the requestBody property.

put file “c:\Temp\test.json” into fileContents
apitestname(requestbody: fileContents)
