Issue in logic app custom action/trigger with dynamic schema.

Question

We have implemented logic app custom action/trigger to show fields based on value selected in drop-down using dynamic schema as mentioned in https://learn.microsoft.com/en-us/connectors/custom-connectors/openapi-extensions#use-dynamic-schema. Now initially when I choose car it loads fields related to car, if I change dropdown value to food, it loads fields related to food and car fields which are previously loading. I want to load fields related to dropdown selected value only.

Answer 1

It sounds like the previous fields aren't getting cleared when switching the dropdown selection. You might need to reset or refresh the dynamic schema when the value changes. Have you tried forcing an update by clearing the existing fields before loading new ones?

This reminds me of how AI-powered editing apps like Photoleap dynamically adjust tools based on selected effects—removing irrelevant options to keep the UI clean. A similar approach might work here, ensuring only relevant fields are displayed when the dropdown value changes.
