[Uganda Project - Technoforte Team] Registrar Signature Not Available in Certificate Template Context

[dibik96]

Current Behaviour

While implementing registrar signature rendering on certificates, the signature image cannot be rendered from the certificate template even though the signature file exists in the system.

Debugging shows:

• {{$lookup $metadata "assignedTo.signature"}} returns empty.
• {{$lookup $metadata "legalStatuses.REGISTERED.createdBySignature"}} returns empty.
• {{$lookup ($action "PRINT_CERTIFICATE") "createdBySignature"}} returns empty.
• User information passed to certificate rendering contains:

{
  "id": "6a1d5f4617ce4b7754d55e74",
  "name": [...],
  "role": "REGISTRATION_OFFICER",
  "signature": undefined
}

• localRegistrar.signature is also null.

However, the signature file is stored in the database as:

{
  "review.signature": {
    "path": "/ocrvs/<file>.png",
    "type": "image/png"
  }
}

Expected Behaviour

Certificate templates should be able to access the registrar/reviewer signature when it has been captured during the workflow.

Technical Investigation

• createdBySignature resolves to undefined.
• Print certificate annotation does not contain review.signature.
• Signature exists in stored annotation data but is not propagated into the certificate rendering context.

Environment

• OpenCRVS Version: v1.9.13
• Country Configuration: Uganda

@dibik96 first of all, a basic question ... have you edited that precise user in the UI to add a transparent PNG signature file for them? This should work for new registrations after that:

{{$lookup $metadata 'legalStatuses.REGISTERED.createdBySignature'}}

In our examples, we use it in an image tag like this:

<image
    id=".."
    x=".."
    y=".."
    width="248"
    height="75"
    xlink:href="{{$lookup $metadata 'legalStatuses.REGISTERED.createdBySignature'}}"
  />

Can you also try this please? It should work for old registrations too:

{{ $lookup ($lookup $metadata 'legalStatuses.REGISTERED.createdBy') "signature" }}

Thank you @euanmillar
