Changelog

[Critical] File Upload/Download Fixes for latest tool with anyOf, oneOf, and allOf Schemas

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.

What Changed

Before (Bug)

File properties inside anyOf, oneOf, or allOf were not detected:

1
// This schema's file_uploadable was NOT being processed
2
inputParameters: {
3
  type: 'object',
4
  properties: {
5
    fileInput: {
6
      anyOf: [
7
        {
8
          type: 'string',
9
          file_uploadable: true  // ❌ Not detected
10
        },
11
        {
12
          type: 'null'
13
        }
14
      ]
15
    }
16
  }
17
}

After (Fixed)

File properties are now correctly detected and processed at any nesting level:

1
// Now properly detected and transformed
2
inputParameters: {
3
  type: 'object',
4
  properties: {
5
    fileInput: {
6
      anyOf: [
7
        {
8
          type: 'string',
9
          file_uploadable: true  // ✅ Detected and processed
10
        },
11
        {
12
          type: 'null'
13
        }
14
      ]
15
    }
16
  }
17
}
