Same problem

Comment From: csterwa

@zhoujh001 Can you please provide more details on the steps to reproduce? It seems like you are connecting to public Pet Store Swagger API and then you are making a call using a model interaction that tries to execute findPetsByTags API route? Is that correct? It seems like this is an issue on the @ivotoby/openapi-mcp-server and sending the tags as an array during that model interaction? And it seems that the MCP server is being connected to from a Spring AI based MCP client, am I correct on this assumption, as well?

Any more details on the specific steps you followed to get this error would be useful.
