    XMLWordPrintable

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Blocker
    • Resolution: Not A Bug
    • Affects Version/s: None
    • Fix Version/s: 1.0.2
    • Component/s: Nuxeo Connector
    • Environment:
      nuxeo-server-10.3-I20181203_2333-tomcat
      arender-rendition:1.0.1-I20181204_1154
      nuxeo-arender:1.0.1-I20181204_1154

      Description

      Calling the Document.ARenderGetDiffUrl operation throws an NPE.

      Steps to reproduce:

      • Set up date-based arender rendtion docker image: 
        docker run -p 8761:8761 --name arender_rendition -it dockerin-arender.nuxeo.com:443/arender-rendition:1.0.1-I20181204_1154
      • nuxeo.conf: 
        org.nuxeo.connect.url=https://nos-preprod-connect.nuxeocloud.com/nuxeo/site/
arender.server.rendition.hosts=http://localhost:8761
arender.server.previewer.host=http://localhost:8080
nuxeo.jwt.secret=test
      • Create a File document with a Word (.docx) file as the main blob.
      • Create another File document with the same Word (.docx) file (only with a few small differences for comparison) as the main blob.
      • Open a terminal and run the following cURL command (replacing the doc IDs with the UUIDs of the documents created and including an authentication token): 
        curl -X POST 'http://localhost:8080/nuxeo/site/automation/Document.ARenderGetDiffUrl' -H 'X-Authentication-Token: <AUTHENTICATION_TOKEN>' -H 'Nuxeo-Transaction-Timeout: 3' -H 'X-NXproperties: *' -H 'X-NXRepository: default' -H 'X-NXVoidOperation: false' -d '{"params":{"leftDocId":"<DOC_UUID_1>","rightDocId":"<DOC_UUID_2>"},"context":{}}'

      => Returns error:

      {"entity-type":"exception","status":500,"message":"java.lang.NullPointerException"}

      => HTTP response:

      {
  "previewerUrl": "http://localhost:8080/ARender/?uuid=Not Found"
}

      => server.log:
