Hi

I'm trying to call an ASP.Net API using REST connector that return a pdf file and attach it to a process, the API is tested and works fine off bonita using Postman.

at the connector output operation I added this code :

import org.bonitasoft.engine.api.ProcessAPI
import org.bonitasoft.engine.bpm.document.Document

byte[] documentContent = bodyAsString.getBytes()
final ProcessAPI processAPI = apiAccessor.getProcessAPI()
 processAPI.attachDocument(processInstanceId,   "settlementReportFileInput",    "merchantReport.pdf",
"application/pdf", documentContent)
return ""

when I try to run it from portal and try to download the attached file from the process overview tab, I got a pdf file that contains empty pages (same pages count as the one generated from the API :) )

when I checked the Bonita Engine Log I found these log

Hello,

There is a WARNING totally at the end of the logs that states that there is a content format issue related to JSON.

It could be related to connector misconfiguration or an unimplemented feature in the REST Connector you are using. If it is the second then you could extend the REST Connector to enable PDF content format.

HIH,
