"{"error":"Error: File could not be found within the upload directory."}"

Hello ,

I am trying to upload my file from client system to open text. so, first i am trying it in postman where i don't want to go with form-data→file approach because i need to write a code in JSON format in my client portal to upload a file , i am uploading the file content to postman and it is showing the below error:File could not be found within the upload directory. .

Do we need to create any directory in open text for the file to be uploaded and then use that path or else how should i move further with this issue.

Please help me with this issue.
