The DuckDuckGo Search Tool is not functional

[poonacha-2]

Bug Description

The error complains that there is a local variable "results" that is accessed before being assigned.

In the Langflow installation, the DuckDuckGoSearch component relies on the duckduckgo_search package, version 6.4.2, which was installed by Langflow.

We identified that the issue lies in the DuckDuckGoSearch component's code at line 43, which is causing the Exception displayed in the Notifications tab when the component is executed.

We suspect that the DuckDuckGoSearch installation may be out of date and the code may need to be updated to use https://pypi.org/project/duckduckgo-search/ version 7.2.1

def build_tool(self) -> Tool:
        wrapper = self._build_wrapper()

        def search_func(query: str, max_results: int = 5, max_snippet_length: int = 100) -> list[dict[str, Any]]:
            try:
                full_results = wrapper.invoke(f"{query} (site:*)")

Reproduction

Steps to Reproduce Bug:

1. just play/run the DuckDuckGoSearch Component
2. View the Notifications and see the results Exception

Expected behavior

When we run the DuckDuckGo tool component, it should build successfully regardless of whether the tool is connected to an agent or is alone.

The error you're encountering with the DuckDuckGoSearch component, where the "results" variable is accessed before being assigned, seems to be related to the version of the duckduckgo_search package being used. The component is currently using version 6.4.2, which might be causing compatibility issues.

To resolve this, you can try updating the duckduckgo_search package to version 7.2.1. This newer version might have changes that address the issue with the "results" variable. You can update the package using pip:

pip install duckduckgo-search==7.2.1

After updating, ensure that the code in the DuckDuckGoSearch component is compatible with the new version of the package. You might need to adjust the method calls or parameters if there were any changes in the package's API between versions 6.4.2 and 7.2.1.

hi!

please follow up on this PR updating the version of duckduckgo component.

#5818

It was tested as tool mode and component and both scenarios are ok.
