FastGPT 4.14.7 Bug Fix Resolutions

This page details all resolved bugs included in FastGPT 4.14.7, for self-hosted users upgrading or validating their deployment. All fixes are pulled directly from the official 4.14.7 release documentation.

Workflow Core Fixes

This section addresses bugs related to workflow design, execution, and import/export:

• Corrected incorrect defaultValueType assignments for global variable types in workflow configurations
• Fixed rendering failures for workflow AI node thinking output
• Resolved missing avatar duplication when converting a simple app to a workflow
• Fixed incorrect identification of reference-type model fields as invalid during workflow import, which cleared those fields
• Restored workflow canvas auto-positioning functionality after switching browser tabs
• Fixed failure of workflow nodes to follow configured error capture branches when an uncaught system error occurs

Tool & MCP Integration Fixes

This section resolves issues with tool calls, MCP integrations, and HTTP tool configuration:

• Implemented precise permission checks for individual MCP sub-tools to block unauthorized access
• Fixed tool call failures caused by Toolkit ToolNames starting with a numeric character
• Resolved JSON parsing errors when creating HTTP tools that included variables in the request body
• Fixed missing file link passing when exposing an Agent via MCP

Mobile Browser Fix

Fixed an issue where first-time visits to share links on iPhone Safari occasionally triggered requests with an empty uid parameter, breaking core functionality for some mobile users.

Validation Steps

Follow these steps to confirm all fixes are active in your 4.14.7 deployment:

1. Navigate to the FastGPT admin dashboard’s version information page to confirm your instance is running version 4.14.7.
2. Validate workflow fixes:
   • Create a test workflow, add an AI node, and confirm thinking output renders properly
   • Convert a simple app to a workflow and verify the avatar is duplicated correctly
   • Import a workflow containing reference-type model fields and confirm no fields are cleared
   • Switch between browser tabs while editing a workflow and confirm canvas auto-positioning works
   • Trigger an uncaught system error in a workflow node and confirm the error capture branch activates
3. Validate tool and integration fixes:
   • Create a toolkit with a tool name starting with a numeric character, confirm successful tool calls
   • Create an HTTP tool with body variables, confirm no JSON parsing errors occur during saving or execution
   • Configure an MCP sub-tool and validate that unauthorized access attempts are blocked
   • Expose an Agent via MCP and confirm file links are correctly passed to connected tools
4. Validate mobile fix: Access a FastGPT share link on an iPhone running Safari, complete the first-time visit flow, and confirm no network requests include an empty uid parameter.
