'Forbidden Error 403: When Uploading file in WebApp

[dipendu_g]

Hi team,

I am using v8, and trying to upload a file to ACC using  /nl/jsp/uploadFile.jsp.

When we use the v5 compatibility fileInput file gets uploaded to the server, while if I use the normal HTML and AJAX to upload the file, it gives an error. ( 403 - Forbidden )

If I use postman / nodejs script to read the file and upload to /nl/jsp/uploadFile.jsp, file gets uploaded properly. 

What could be the reason 403 error, I tried with __sessiontoken cookie, __securitytoken, and also with Bearer Token, which works in postman, but not within the WebApp

Please help 

Regards,

DG

Hello @dipendu_g Are you using correct form encoding to upload file via Ajax?

Here is what is used in form to upload images.

enctype="multipart/form-data"

Hi @_Manoj_Kumar_ , 

I am using FormData to store the uploaded file and then using fetch to upload. 

await fetch('/nl/jsp/uploadFile.jsp', {
                    method: "POST",                     
                    body: formData,
                    headers:myHeaders
            });

Hi @_Manoj_Kumar_ 

let formData = new FormData();

formData.append("file",files[0])

Hello @dipendu_g  Do you see the same payload value in webApp with v5?

Depending on where the file is store the the payload field can change.

Hi @_Manoj_Kumar_ ,

I can see payload with v5, file approach. Here we are creating our own form. The v5 file upload works
