Invalid schema for function hubspot-search-objects

[clemenspeters]

When using MCPServerStdio with @openai/agents I get

error: {
message: "Invalid schema for function 'hubspot_search_objects': In context=('properties', 'filterGroups', 'items', 'properties', 'filters', 'items', 'properties', 'values'), array schema missing items.",
type: 'invalid_request_error',
param: 'tools[2].parameters',
code: 'invalid_function_parameters'
}

Current workaround:

    toolFilter: createMCPToolStaticFilter({
        blocked: ['hubspot-search-objects'],
    }),

fixes the issue by ignoring that function
