Hi, we found a bug in tLifererayInput component when working with openAPI MODULE PATH /headless-admin-taxonomy/v1.0 and the operation path "/taxonomy-vocabularies/{taxonomyVocabularyId}/taxonomy-categories"

When we call the method setting the parameter taxomonyVocabularyId with and existent vocabulary id, it seems that the API call is correct, but there is a bug in tLifererayInput component deserializing JSON response.

The same request executed on a REST Client work correctly and return a valid response.

The exception is:
