Adding a new file to an existing object (javascript)

Gilles Gerlinger

Hi,

I succeeded to update an existing file attached to an object via the API "REST/objects/0/{checkedOutObjectVersion.ObjVer.ID}/files/{checkedOutObjectVersion.Files[0].ID}/content.aspx?_method=PUT", although that was tough. I need now to add a new file to an existing object. From the C# example at https://developer.m-files.com/APIs/REST-API/Updating-Objects/#updating-an-existing-file, I figured out that the API is "REST/objects/0/{checkedOutObjectVersion.ObjVer.ID}/{checkedOutObjectVersion.ObjVer.Version}/files/upload.aspx". However, it is not clear at all how I pass the file name and file extension through the API, mostly since I am using an application/octet-stream content type where I cannot mix JSON data and binary data.

Any help would be appreciated, as well as javascript examples.

Thank you in advance,

Gilles Gerlinger

    By the way, this is the error message returned by the APi : "The current endpoint is part of the 'MFWA' extension. Use 'X-Extensions' header or 'extensions' query parameter to specify the extension."

    To be more precise:

    This is the object sent after the file content is successfully uploaded:

    {UploadID: 4, Size: 1473469, FileInformationType: 0, Extension: 'zip', Title: 'SCORM_What_5G_is_and_what_it_isnt_TD10721-W-1800-kghuhxxs'}

    and the error message:

    {
      Status: 405,
      URL: '/objects/0/60893/latest/files/upload',
      Method: 'POST',
      Exception: {
        Name: 'NotSupportedException',
        Message: "The current endpoint is part of the 'MFWA' extension. Use 'X-Extensions' header or 'extensions' query parameter to specify the extension."
      },
      Stack: 'Error reference ID: 4e095967-d8d8-4d78-89e2-2118ee0901b3',
      Message: "The current endpoint is part of the 'MFWA' extension. Use 'X-Extensions' header or 'extensions' query parameter to specify the extension.",
      IsLoggedToVault: true,
      IsLoggedToApplication: true,
      ExceptionName: 'NotSupportedException'
    }

    File upload with REST/files seems OK. It returned the following data:

    {"UploadID":10,"Size":1473469,"FileInformationType":0}

    After adding Title and Extension it becomes:

    {"UploadID":10,"Size":1473469,"FileInformationType":0,"Extension":"zip","Title":"SCORM_What_5G_is_and_what_it_isnt_TD10721-W-1800-kghuhxxs"}

    Then after adding the file to the object, here is the error message I have:

    {
      Status: 400,
      URL: '/objects/0/60893/latest/files/upload',
      Method: 'POST',
      Exception: { Name: 'ArgumentException', Message: 'Malformed data.' },
      Stack: 'Error reference ID: 7e75e1c5-f3b5-4754-8f50-061da13262d3',
      Message: 'Malformed data.',
      IsLoggedToVault: true,
      IsLoggedToApplication: true,
      ExceptionName: 'ArgumentException'
    }

    I finally made it by calling the API "

    objects/${object.Type}/${object.ID}/latest/files/${uploadID}/title?_method=PUT to change the title of the uploaded file (which was Unnamed). This was not part of the C# example, I had to dig into the API docuemtation to find this...

    So the api loads the unnamed file, and later you change the title with another api call?, i have a very similar issue whit python

    Indeed, I had to deep dive into the API documentation and make various tries before I found this way to add a new file to an object...
