Upload document via CreateAndImportDocument.svc/EdmFileSet from Logic App Custom Connector

Question

Based on an OpenAPI v2 definition of the CreateAndImportDocument API I have created a custom connector in Azure Logic Apps. The creation of the document works fine, but I fail on the upload (i.e. patch) step.

The raw input shows

1    "body": {
2        "FileData":"......."

...however the API seems to only expect the raw file as body. Have changed the swagger definition of the filedata parameter to file, but still my input looks something like this:

1    "body": {
2
3        "$content-type": "multipart/form-data",
4
5        "$multipart": [
6
7            {
8
9                "body": {
10
11                    "$content-type": "image/jpeg",
12
13                    "$content": "..............."
14
15                },
16
17                "headers": {
18
19                    "Content-Disposition": "form-data; name=\"FileData\""
20
21                }
22
23            }
24
25        ]
26
27    }

IFS Cloud response:

1      {
2        "code": "UNSUPPORTED_CONTENT_TYPE",
3        "message": "The content type 'multipart/form-data;boundary=\"d2956e58-622f-4b26-bbdf-55b61f018754\"' is not supported."
4      }

I didn’t find a different way of sending my file content as request body. Anyone any idea how to solve this?

Hi Alexander,I don't have any experience with Azure Logic Apps, so I cannot give you a recipe on how to upload a file there.I could be wrong but I think the we are not uploading files using the multipart/form-data content type. I have an old bash script (see below) that uses curl to upload a file and the actual upload (patch request) is quite small.echo Creating document...ROOTURL=https://SERVER:PORTDOCCLASS=200# AUTH is a Base64-encoded version of username:password.# Below the username and password is jackie:jackieAUTH=amFja2llOmphY2tpZQ==docNo=$(curl -s -k --location --request POST $ROOTURL'/int/ifsapplications/projection/v1/CreateAndImportDocument.svc/CreateDocument' \ --header 'Authorization: Basic '$AUTH \ --header 'Content-Type: application/json' \ --data-raw '{"DocClass" : "'$DOCCLASS'", "DocNo" : null, "DocSheet" : null, "DocRev" : null, "Title" : " Test Document", "BookingList" : null, "Id1" : null, "Id2" : null , "CreateFileRef" : "YES"}' | grep -Po '"DocNo":"[0-9]+"' | grep -Po '[0-9]+')echo Document $docNo created.
