Are there any known limitations or issues when printing webmaps containing Subtype Group Layers?

In general, there are no known limitations when printing Subtype Group Layers (SGLs) with the VertiGIS Studio Printing Engine (VSPE).

However, there is a known issue affecting VSPE deployments on ArcGIS Enterprise 11.4 and earlier. Modern web applications such as VertiGIS Studio Web use the ArcGIS Maps SDK for JavaScript 4.x, which relies on OAuth 2.0 Authorization Code Flow access tokens. To maintain user authentication during extended web sessions, these access tokens are automatically refreshed at regular intervals (30 minutes by default).

As a result, print requests may contain newly refreshed access tokens for protected Subtype Group Layers. In affected ArcGIS Enterprise versions, VSPE may not correctly handle these refreshed tokens, which can lead to missing Subtype Group Layer content in printed output. The issue can affect both the user who initiated the print job and other portal users, and may occur with any subsequent print request.

Once the issue has occurred, recovery typically requires either:

• Restarting the VSPE service on the federated ArcGIS Server, or
• Configuring short-lived VSPE worker instances (generally not recommended for production environments).

To avoid this issue, it is recommended to use ArcGIS Enterprise 11.5 or later, where the underlying problem has been addressed.
