--- title: "File Upload/Download Fixes for latest tool with anyOf, oneOf, and allOf Schemas" description: "File handling modifiers now properly handle nested anyOf, oneOf, and allOf JSON Schema declarations" date: "2026-01-20" --- ## Version Information ### TypeScript/JavaScript - Package: `@composio/core` and provider packages - Version: `0.5.3`+ ### Python - Package: `composio` and provider packages - Version: `0.10.8`+ --- The file handling modifiers now properly handle `file_uploadable` and `file_downloadable` properties nested within `anyOf`, `oneOf`, and `allOf` JSON Schema declarations. Previously, only direct child properties (and partial `allOf` support) were detected for file upload/download transformations. We recommend updating to version `0.5.3` (TypeScript) or `0.10.8` (Python) or later to ensure file uploads and downloads work correctly with tools that use union or intersection types in their schemas. ## What Changed ### Before (Bug) File properties inside `anyOf`, `oneOf`, or `allOf` were not detected: ```typescript // @noErrors // This schema's file_uploadable was NOT being processed inputParameters: { type: 'object', properties: { fileInput: { anyOf: [ { type: 'string', file_uploadable: true // ❌ Not detected }, { type: 'null' } ] } } } ``` ### After (Fixed) File properties are now correctly detected and processed at any nesting level: ```typescript // @noErrors // Now properly detected and transformed inputParameters: { type: 'object', properties: { fileInput: { anyOf: [ { type: 'string', file_uploadable: true // ✅ Detected and processed }, { type: 'null' } ] } } } ``` ## Affected Scenarios | Scenario | Before | After | |----------|--------|-------| | `file_uploadable` in `anyOf` | Not detected | ✅ Works | | `file_uploadable` in `oneOf` | Not detected | ✅ Works | | `file_uploadable` in `allOf` | Not detected | ✅ Works | | `file_downloadable` in `anyOf` | Not detected | ✅ Works | | `file_downloadable` in `oneOf` | Not detected | ✅ Works | | `file_downloadable` in `allOf` | Not detected | ✅ Works | | Nested objects inside union types | Not detected | ✅ Works | | Array items with union types | Not detected | ✅ Works | ## How to Update ### TypeScript/JavaScript ```bash npm update @composio/core@latest ``` ```bash pnpm update @composio/core@latest ``` ```bash yarn upgrade @composio/core@latest ``` ### Python ```bash pip install --upgrade composio ``` ```bash uv pip install --upgrade composio ``` ```bash poetry update composio ``` ## Backward Compatibility This release is fully backward compatible: - All existing code continues to work without modifications - No migration required - File upload/download for direct properties continues to work as before - The fix only adds support for previously unsupported schema patterns ## Impact Summary | Change | Runtime Breaking | TypeScript Breaking | Migration Required | |--------|------------------|---------------------|-------------------| | `anyOf` support for file uploads | No | No | No | | `oneOf` support for file uploads | No | No | No | | `allOf` support for file uploads | No | No | No | | `anyOf` support for file downloads | No | No | No | | `oneOf` support for file downloads | No | No | No | | `allOf` support for file downloads | No | No | No |
