I'm getting this error in my application

I call the interface with the upload field in the forms and at one of the primary buttons i call the function a!submitUploadedFiles(). "at function a!buttonWidget".

I cant understand what can i do for this to work. Already checked the version of the buttons and forms. It's all up to date.

Can some help me ?

I forgot to say. My objective is to save the size of the document instantly after the upload.

The fuction submitUploadedFiles() let me use the fv!file.size only in validations... But i need to save it... Appian could make it to the saveInto too :D :D

I've been asking for this feature for years. You should go and upvote (and comment on) my Old Feature Request Thread, so more people will see it.

The answer to your original question is: a!submitUploadedFiles() (sadly) can not be used in a process task (task or start form) at all. You'll need a different work-around.

I tried to replicate your requirement, have a look at it(v25.3).

a!localVariables(
  local!document,
  local!documentSize,

  a!formLayout(
    contents: {
      a!fileUploadField(
        label: "Upload Document",
        target: {},
        /*Replace this with you target folder*/
        value: local!document,
        saveInto: {
          local!document,
          /* Handle list of documents */
          a!save(
            local!documentSize,
            if(
              or(isnull(local!document), length(local!document) = 0),
              null,
              document(local!document[1], "size")  /* Get first document */
            )
          )
        },
        maxSelections: 1  /* Limit to single file */
      ),

      /* Display the captured size */
      a!textField(
        label: "Document Size (bytes)",
        value: local!documentSize,
        readOnly: true
      )
    },

    buttons: a!buttonLayout(
      primaryButtons: {
        a!buttonWidget(
          label: "Submit",
          submit: true,
          saveInto: {
            /* Your other save logic here */
          }
        )
      }
    )
  )
)
