Getting "JSON malformed" error when trying to PUT data via HTTP

[Anonymous]

Hi,

I'm trying to send a simple JSON via HTTP "PUT" command, but keep getting the following error:

{

  "errortext": "JSON malformed in line 1, position 1. JSON malformed. Was expecting: \" 0-9 null true false { [.",

  "errornumber": 7

}

The very original JSON which have worked on other software is (host censored):

PUT /connector/relations/handleRelation HTTP/1.1
Host: XXX.XXXX.fi
Authorization: Basic c29hcDpzb2Fw
Content-Length: 145
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="data"

{"company": "Test Company"}
----WebKitFormBoundary7MA4YWxkTrZu0gW

I have tried to simply copy/paste this into body field, and also tried to type the headers into the "Headers" field on HTTP task but no change whatsoever.

Does anyone have idea what could cause the "JSON malformed" error, and what would be the right structure for the JSON?

Thanks in advance!

Hello @Anonymous,

I think the body of your request should contain

{"company": "Test Company"}

The rest, like Content-Type, Content-Dispostion etc. should go into the headers.

Hello @joe_hannes_col !

Thanks for the reply, but I just actually found a "workaround" to this with my colleague.

We used POST instead of PUT and used the webhook to get things working:

Data is taken from chat bot working on our ms teams (objects are in Finnish)

Seems like this HTTP tool doesn't support form-data as it is?

Great you made it work, @Anonymous!

I'm not aware of any limitations regarding the use of form-data, but my requests have always been in JSON so far 🙂
