Overview
This document details all bug fixes included in the FastGPT v4.15.07 self-hosted upgrade release. These fixes target stability and usability issues reported by self-hosted users during workflow configuration, agent integration, and in-editor text interaction. All changes are limited to resolving specific edge cases, with no breaking changes to supported public APIs or core workflow execution logic.
Tabulated Bug Fix Summary
The following table lists each resolved issue, its associated technical context, and the operational impact it addressed:
| Fix Reference | Resolved Issue | Operational Impact |
|---|---|---|
| 1 | Historical V1 workflow data could fail validation under the new save payload structure | Prevents validation errors when loading or updating older workflow versions |
| 2 | Dirty FlowNodeInputTypeEnum.*, FlowNodeOutputTypeEnum.*, and WorkflowIOValueTypeEnum.* expression strings in workflow node configuration | Eliminates broken input rendering and failed IO type checks for workflow nodes |
| 3 | AgentV2 MCP not being able to retrieve schemas | Restores proper schema retrieval for AgentV2 deployments using MCP integrations |
| 4 | Workflow text boxes where pressing Ctrl+C while selecting text could be intercepted by node copy handling | Restores standard text copy functionality for workflow text input fields |
Post-Upgrade Validation Steps
To confirm all resolved fixes are active after upgrading to v4.15.07, follow these targeted checks:
- Load a previously saved V1 workflow, then attempt to save the workflow without edits to confirm no validation errors occur.
- Edit a workflow node that uses input or output type enums, then verify the node’s configuration UI renders correctly without broken type check logic.
- Deploy an AgentV2 integration with MCP, then confirm the schema list loads without failure.
- Select text within any workflow text input field, press Ctrl+C, and paste the text into an external editor to confirm the copy operation works as expected.
