Help with multipart upload about react-native-uploader

[aroth]

Hi @rgoldiez -- how far are you getting with this?

@aroth - Thanks for the response. Still stuck.

Here's what I'm sending

{ url: 'https://bots.my.salesforce.com/services/data/v36.0/connect/communities/0DB6100000000KLGAY/chatter/feed-elements',
  files: 
   [ { name: 'feedElementFileUpload',
       filename: 'image.png',
       filepath: 'file:///Users/rgoldiez/Library/Developer/CoreSimulator/Devices/4D36D070-BD5E-4C17-BF64-28331FD9A5DD/data/Containers/Data/Application/ABCFF4C9-C6E1-42E7-990D-8A3377CA2F30/Documents/images/44077641-6762-4CF3-AB27-37BC5021D4A1.jpg',
       filetype: 'image/png' } ],
  method: 'POST',
  headers: 
   { Accept: 'application/json',
     Authorization: 'Bearer [__removed token__]' },
  params: 
   { 'Content-Type': 'application/json; charset=UTF-8',
     subjectId: 'a0561000001fZIlAAM',
     capabilities: { content: { description: 'Test file upload', title: 'image.jpg' } },
     feedElementType: 'FeedItem' } }

I'm getting the follow response back from salesforce.

{
  "errorCode":"POST_BODY_PARSE_ERROR",
  "message":"Binary data included but file attachment information is missing. If providing rich JSON/XML input in multipart REST, make sure to include Content-Type header in the part."
}

Any help is greatly appreciated! Note that I'm able to use this component to upload a user profile attachment to salesforce, but that doesn't required a multipart form message... it's just a simple upload to a REST endpoint.

@aroth - any ideas?

@rgoldiez I've taken on some new work and don't have much time to dig into this specific scenario. It appears that others have had similar issues when posting data to the Salesforce/Chatter API. You can review a few of these here:

https://www.google.com/search?q=%22Binary+data+included+but+file+attachment+information+is+missing%22&oq=%22Binary+data+included+but+file+attachment+information+is+missing%22&aqs=chrome..69i57l2.567j0j7&sourceid=chrome&es_sm=91&ie=UTF-8

It's likely header or param naming issues as other libraries are returning the same response. Or it could be a limitation with this library -- I am not certain. Here is a working code example in Java:

I think it would be useful to determine what react-native-uploader is generating and compare that to input that the Salesforce API is expecting.
