Re: Creating File: File is mandatory

Anonymous · ‎02-08-2018

Hello,

I'm following the documentation for creating Files in the Asset database from here: http://developers.marketo.com/rest-api/assets/files/#create_and_update

So I'm using a images and files folder, and trying to create a new file (it currently has no files).

I copy and pasted the body given by the documentation under Create

With the following header:

I'm getting "File is mandatory".

Is there something else I'm missing?

You'd highlight that code as Plain (as MIME isn't a supported syntax) like so:

Which turns it into:

------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="file"; filename="marketo.html"
Content-Type: text/html
<html>
<body>
<h1>Test Page - marketo.html</h1>
</body>
</html>
------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="name"
marketo.html
------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="folder"
{"id":436,"type":"Folder"}
------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="description"
This is a test file
------WebKitFormBoundary2VyWOacQSupl4gUL—

The #set() syntax is literal Velocity/Java code. It's not part of using the hightlighter.

Now we can look at the payload properly and see there are several things wrong with it.

First, this boundary is incorrect for your payload (this is exactly why a monospace font is used for code):

multipart/form-data; boundary=------WebKitFormBoundary2VyWOacQSupl4gUL

You have 6 hyphens:

------WebKit...

And your actual MIME parts also have 6 hyphens, which is incorrect:

------WebKit...

In the body, you want 8 hyphens, the constant prefix of -- followed by the boundary.

Second, after the final boundary, you need to have an additional suffix -- (you have an em-dash there instead).

Third, you need to have a line break (CRLF) after the header section of each MIME part.

So the correct format is:

--------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="file"; filename="marketo.html"
Content-Type: text/html
<html>
<body>
<h1>Test Page - marketo.html</h1>
</body>
</html>
--------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="name"
marketo.html
--------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="folder"
{ "id":1187, "type":"Folder" }
--------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="description"
This is a test file
--------WebKitFormBoundary2VyWOacQSupl4gUL--

Can you please paste actual code using the Advanced Editor's syntax highlighter? Troubleshooting a screenshot is really... suboptimal.

Which parts of the code? They're all directly copy and pasted from the examples in the market documentation. The body is from the body provided under the create and update section of the document. I haven't written any code myself, aside from the header

#set($this = "multipart/form-data; boundary=------WebKitFormBoundary2VyWOacQSupl4gUL")

SanfordWhiteman · ‎02-09-2018

All the code. If I want to reproduce your problem I can't copy the screenshot.

Here's the request body:

#set($this = "

<body>

Content-Disposition: form-data; name="name"

marketo.html

------WebKitFormBoundary2VyWOacQSupl4gUL

Content-Disposition: form-data; name="folder"

{"id":436,"type":"Folder"}

This worked, many thanks!

SanfordWhiteman · ‎02-15-2018

Cool, hopefully others will find this thread instead of copying the code examples from the docs. I assume maybe an editor (not an coder) stripped out the all-important line breaks to save space and didn't know hyphens are special...

Hi Jerry,

I am still facing the same issue. Could you please share the snippet of the code.

Thanks,

Shruti

See my correct answer for a proper payload.
