FYI, I have updated the sample setup to latest OHIF beta + latest Orthanc version. Still the same issue.

I'm attaching the sample PDF file that I use. Study With PDF.zip

Once you have launched the setup and uploaded the file in Orthanc,
OHIF v2 shows the PDF: http://localhost:3002/viewer/1.2.276.0.7230010.3.1.2.2344313775.14992.1458058363.6979
OHIF v3 does not show the PDF: http://localhost:3003/viewer?StudyInstanceUIDs=1.2.276.0.7230010.3.1.2.2344313775.14992.1458058363.6979

The wrong BulkDataURI is being returned by the server - if you are going to use absolute URIs, you have to have the right absolute URI.
Also, when I manually adjusted the URL to be correct, then there are a couple of settings which aren't correct in the data source. I've attached my working datasource to this issue. Sorry, that won't paste, adding a copy of it:

window.config = {
  routerBasename: '/',
  extensions: [],
  modes: [],
  showStudyList: true,
  dataSources: [
    {
      friendlyName: 'Orthanc local',
      namespace: '@ohif/extension-default.dataSourcesModule.dicomweb',
      sourceName: 'orthanc',
      configuration: {
        name: 'orthanc',

        wadoUriRoot: '/orthanc/dicom-web',
        qidoRoot: '/orthanc/dicom-web',
        wadoRoot: '/orthanc/dicom-web',

        qidoSupportsIncludeField: false,
        supportsReject: false,
        imageRendering: 'wadors',
        thumbnailRendering: 'wadors',
        enableStudyLazyLoad: true,
        supportsFuzzyMatching: false,
        supportsWildcard: true,
        staticWado: true,
        // Note orthanc does not have a singlepart retrieve for pdf or video, so exclude those two.
        singlepart: 'bulkdata',
        // The separate retrieve/decoding of bulkdata URIs to internal blobs which are URL accessible is addressed with this configuration:
        bulkDataURI: {
          enabled: true,
          relativeResolution: 'studies',
          // This is an example config that could potentially be used to fix the retrieve URL
          startsWith: 'http://localhost/',
          prefixWith: '/orthanc/',
        },
        acceptHeader: ['multipart/related; type=application/octet-stream; transfer-syntax=*']
      },
    }],
  defaultDataSourceName: 'orthanc',
};

I added a small PR with a working sample configuration file, and a small change to allow fixing the broken orthanc URLs.

The response that docker is returning is for the metadata for the PDF is below, when requesting on port 3003 eg on http://localhost:3003/orthanc/dicom-web/studies/..../series/..../metadata one gets
"00420011" :
{
"BulkDataURI" : "http://localhost/dicom-web/studies/1.2.276.0.7230010.3.1.2.2344313775.14992.1458058363.6979/series/1.2.276.0.7230010.3.1.3.1901948703.36080.1484835349.617/instances/1.2.276.0.7230010.3.1.4.1901948703.36080.1484835349.618/bulk/00420011",
"vr" : "OB"
},

However, there is no server running on http://localhost port 80.
For the server running on port 3003, the path would be:
http://localhost:3003/orthanc/dicom-web/studies/1.2.276.0.7230010.3.1.2.2344313775.14992.1458058363.6979/series/1.2.276.0.7230010.3.1.3.1901948703.36080.1484835349.617/instances/1.2.276.0.7230010.3.1.4.1901948703.36080.1484835349.618/bulk/00420011

Note the /orthanc/ as well as the port number.

Other acceptable URLs would be:
instances/1.2.276.0.7230010.3.1.4.1901948703.36080.1484835349.618/bulk/00420011

or the relative URL:
/orthanc/dicom-web/studies/1.2.276.0.7230010.3.1.2.2344313775.14992.1458058363.6979/series/1.2.276.0.7230010.3.1.3.1901948703.36080.1484835349.617/instances/1.2.276.0.7230010.3.1.4.1901948703.36080.1484835349.618/bulk/00420011

It is possible that last URL will double up on the /orthanc/dicom-web/ port - if so, this URL should work (but should be fixed as this isn't actually standards compliant - the two above ARE standards compliant)
/studies/1.2.276.0.7230010.3.1.2.2344313775.14992.1458058363.6979/series/1.2.276.0.7230010.3.1.3.1901948703.36080.1484835349.617/instances/1.2.276.0.7230010.3.1.4.1901948703.36080.1484835349.618/bulk/00420011

I would suggest the instances version of it.

I confirm I was able to update our test setup with the latest build and it works. Thanks !

Hi @sedghi and @wayfarer3130

I'm not sure we are 100% done with this issue :-(

As mentioned in my previous comment, one of our test-setup works fine with v3.9.0-beta-56. Note that, in this setup, I'm using the standard Docker image from OHIF and therefore serving OHIF on a dedicated nginx server on http://localhost:3003 with a reverse-proxy forwarding /orthanc to http://orthanc:8042. This orthanc does not know that it is served at /orthanc and that's the reason why we need this new bulkDataURI.startsWith and bulkDataURI.prefixWith to fix the Orthanc bulkdDataURIs. Everything works fine in this setup !

However, when we deploy OHIF and Orthanc together (e.g in this setup), we usually have our own nginx in front of both OHIF and Orthanc. OHIF is reversed proxied at /ohif and Orthanc at /orthanc.
For this, we build our own version of OHIF with this Dockerfile - the only relevant difference with your build process is the PUBLIC_URL=/ohif/ option.
In this setup, Orthanc is aware that it is served at /orthanc and thanks to this configuration: ORTHANC__DICOM_WEB__PUBLIC_ROOT: "/orthanc-container/dicom-web/" the bulkDataURIs are correct. However, in this setup, PDFs are not showing.

Steps to reproduce:

• clone this repo and cd into docker/ohif
• docker compose up --build
• upload the sample with PDF study in http://localhost/orthanc-container/ui/app/
• open the ohif viewer through http://localhost/ohif/viewer?StudyInstanceUIDs=1.2.276.0.7230010.3.1.2.2344313775.14992.1458058363.6979. It seems it's not even trying to load the embedded PDF
• by manually downloading the content of the BulkDataUri, curl http://localhost/orthanc-container/dicom-web/studies/1.2.276.0.7230010.3.1.2.2344313775.14992.1458058363.6979/series/1.2.276.0.7230010.3.1.3.1901948703.36080.1484835349.617/instances/1.2.276.0.7230010.3.1.4.1901948703.36080.1484835349.618/bulk/00420011 > /tmp/test.pdf we get a valid PDF file

Thanks for your help !
