📄 Description

Summary

The else block for non-native function calling in process_chat_payload was indented at the same level as if tools_dict:, incorrectly pairing it with the outer check instead of the inner if function_calling == "native" check.

Before (broken):

if tools_dict:
    if metadata.get("params", {}).get("function_calling") == "native":
        # native setup...
        ]

else:  # ← paired with 'if tools_dict:' — runs when tools_dict is EMPTY
    # non-native handler never runs when tools are present
    try:
        form_data, flags = await chat_completion_tools_handler(...)

After (fixed):

if tools_dict:
    if metadata.get("params", {}).get("function_calling") == "native":
        # native setup...
        ]

    else:  # ← correctly paired with inner 'if native:' — runs when tools present and not native
        try:
            form_data, flags = await chat_completion_tools_handler(...)

Impact

Non-native (default/prompt-based) tool calling was completely broken when any tools were present — the handler was never called.
The non-native handler was incorrectly invoked when tools_dict was empty (no tools), where it would be a no-op at best.

Test plan

Enable a tool in OpenWebUI with function calling set to default (non-native)
Confirm the tool is actually called during a chat completion
Enable a tool with function calling set to native — confirm it still works
