String url = 'https://upload.box.com/api/2.0/files/upload_sessions';
Http p1 = new Http();
HttpRequest request1 = new HttpRequest();
request1.setEndpoint(url);
request1.setMethod('POST');
request1.setHeader('Contect-type','application/json');
request1.setHeader('Content-Length', String.valueOf(jsonBody.length()));
request1.setHeader('Authorization','Bearer '+boxData.Access_Token__c);

Hi Sandip

I think you get the error message because you are including the 'Content-length' header in your request and it doesn't match the size. You shouldn't have to include this header. See https://developer.box.com/reference/post-files-upload-sessions for required headers and request body. Try to remove it and see if that solves your problem
