- API and Permission Management: Resolves gaps in API security, billing accuracy, and permission filtering for evaluation workflows.
- Data and Tool Integration: Addresses encoding errors during document upload and schema consistency issues for integrated tools.
Full Detailed Fixed Issue Reference
All resolved bugs are documented below in a structured reference table for quick lookup:
| Issue Domain | Resolved Bug Description |
|---|---|
| Chat Agent Mode | Model state reset after page refresh |
| API Security | Missing permission validation across multiple platform APIs |
| Billing & Dataset API | Incorrect billing calculation in dataset data push API |
| Document Upload | Garbled Chinese characters in uploaded Markdown files due to ASCII encoding misdetection |
| Code Execution Node | Python code execution ignoring configured parameters when input is empty |
| Workflow Global Variables | Multi-select enum default values not cleared when an enum entry is removed |
| Sub-Workflow Nodes | Default global variable values not displayed when adding a sub-workflow node |
