Workflow Engine 21.1.1

May 25, 2026

Overview

Workflow Engine 21.1.1 is a targeted hotfix release focused on correcting JSON parameter handling in the HTTP Request action so form data is preserved when process values are injected into the request parameters field.

Why update

• Fix HTTP Request parameter handling when you pass a JSON string through @Value, preventing existing form data from being overwritten unexpectedly.
• Restore correct behavior when you pass a JObject through @Value:json to the HTTP Request action.
• Reduce the risk of corrupted outbound request payloads in workflows that build HTTP parameters from form data.

Key features

• HTTP Request action parameter merging now preserves existing form data when process values are injected into the Parameters field.
• JSON input is handled consistently for both raw JSON string values and JObject values passed through Workflow Engine parameter substitution.

Changelog

Update instructions

• All packages: update Workflow Engine packages to version 21.1.1.
• If you use the HTTP Request action and populate its Parameters field from process parameters with @Value or @Value:json, prioritize this update.
• No database migration or other package-specific migration steps are required for this release.

Bug fixes

• HTTP Request action: fixed inconsistent parsing in the Parameters field when values are injected from process parameters. JSON strings passed through @Value and JObject values passed through @Value:json no longer overwrite existing form data during parameter substitution.
