Apryse WebViewer in Appian showing dot-notation component names instead of user-friendly labels

WebViewer Version: 11.9.0

Do you have an issue with a specific file(s)?
I am testing the Edit PDF functionality. Hence the issue is currently with PDFs.
Can you reproduce using one of our samples or online demos?
Yes. Even if I take the Modular UI configuration from the demo, there are a lot of fields that show dot notation names.
Are you using the WebViewer server?
No I am not using WebViewer server.
Does the issue only happen on certain browsers?
No. I have tested this on Chrose and Microsoft Edge and I can see the issue appear on both.
Is your issue related to a front-end framework?
I am not sure at this point.
Is your issue related to annotations?
I dont think so.

Please give a brief summary of your issue:
Apryse WebViewer in Appian showing dot-notation component names instead of user-friendly labels

Please describe your issue and provide steps to reproduce it:
I am integrating the Apryse WebViewer Plugin for Appian using a demo license, and I’m encountering an issue where the names of the UI components in the WebViewer toolbar and menus are not displaying the usual user‑friendly labels.

Instead of readable labels like “Highlight”, “Underline”, “Shapes”, etc., the UI displays the internal dot-notation identifiers, for example:
annotations.createToolGroup annotations.createToolGroupErase annotations.createToolGroupShapes

I’m aware that Appian’s Modular UI Component allows developers to override or manually set labels, but in my case I don’t want to customize them. I want to use the default Apryse-provided labels.

Steps to Reproduce

  1. Install the Apryse Connected System and WebViewer Component
    Follow the official Apryse installation guide for Appian to install both the Connected System and the WebViewer plugin.

  2. Use the Apryse WebViewer in an Appian interface with a Demo License Key
    Load any PDF using the WebViewer component configured with a demo key.
    The toolbar and context menu labels appear in dot-notation instead of user-friendly names.

Please provide a link to a minimal sample where the issue is reproducible:
I am using the default demo sample. The issue is visible when the Webviewer loads.

Hi there,

This typically happens when the language file is not fetched from your application.

Please check the network panel and see if any file such as ‘translation-en’ is blocked from being fetched.

Best regards,
