Error: `There are duplicate parameter values` encountered when parsing OpenAPI spec

Description

I'm currently developing a Ballerina client connector for the SmartSheet REST API [1]. While parsing the official OpenAPI spec provided by SmartSheet, I’m encountering the following error:

paths.'/favorites'(get).parameters. There are duplicate parameter values
paths.'/favorites'(get).parameters. There are duplicate parameter values
paths.'/favorites/{favoriteType}'. There are duplicate parameter values
...

I've attached both the OpenAPI specification and the error log generated during parsing for reference.
