ValueError: invalid literal for int() with base 10:

[firebird199]

Bug Description

When I execute the command pip install langflow -U, the entire installation process goes smoothly. However, after running langflow run, as expected, a web page automatically opens for the user to design the workflow. After filling in the required settings such as the api_key, when I try to drag any model from the Model section, I encounter the following error: ValueError: invalid literal for int() with base 10:. The specific log includes the following:

                         ValueError: invalid literal for int() with base 10: ''

Hey @firebird199! 👋 I'm here to help you with any bugs, questions, or contributions! Let's squash those bugs together while we wait for a human maintainer.

The error you're encountering, ValueError: invalid literal for int() with base 10: '', occurs because the code is attempting to convert an empty string to an integer. This happens in the custom_component_update function when processing the value_dict object.

To resolve this issue, you need to ensure that the value_dict.get("value") is not an empty string before attempting to convert it to an integer. You can add a validation check to handle this case.

Here's a potential fix for the issue in the custom_component_update function:

params = {
    key: value_dict.get("value")
    if value_dict.get("_input_type") != "IntInput"
    else (
        int(value_dict.get("value")) if value_dict.get("value") else None  # Add this check
    )
    if value_dict.get("_input_type") != "FloatInput"
    else float(value_dict.get("value"))  # type: ignore
}

This modification ensures that if value_dict.get("value") is an empty string, it will not attempt to convert it to an integer, thus avoiding the ValueError.

You can apply this change to your local copy of the endpoints.py file and see if it resolves the issue. If the problem persists, please provide additional details or logs for further assistance.

no it wasn't. same error for me when adding local ollama module and then clicking on Model Name selector

Hi, @secretgspot . I hope you're doing well.

Which version are you using?
The fix I mentioned is currently only available in the main branch. So, if you're using v1.0.16 or earlier, you'll still encounter the error.

You can either wait for the v1.0.17 release or clone the repository directly to get the fix.
