How to handle errors when using the categorize component?

From downstream components: ERROR: Can't inference the where the component input is. Please identify whose output is this component's input.

I found a similar closed issue where the suggested solution was to pull the dev version of the Docker image again, as recent fixes were made ^[1].

To handle the error "Can't inference where the component input is" when using the categorize component, ensure the following:

1. Verify that the categorize component is correctly connected to its upstream components. Check that the connection is properly established in your setup.

2. Ensure that the upstream components produce outputs that can be used as inputs for the categorize component. Confirm that the upstream component is correctly configured to provide the necessary output.

3. Check the logic that populates upstream_outs to ensure it correctly identifies and appends the necessary outputs from upstream components. Make sure the input variables are correctly added in the Input section of the categorize component.

4. Review the categorize component's configuration to ensure that each category has a name, description, examples, and the corresponding next component specified.

Adjust the component connections and logic to ensure proper data flow, and review the configurations for the categorize component, including the model settings, to ensure they are correctly set up for your use case ^[2][3][4].

There was no problem with version v0.17.2, but this issue only appeared after upgrading to v0.18.0.
So I think it's a bug in the new version.

Rolling back v0.17.2, this issue disappeared.
