hey. I completely trimmed my MCP result.  
this is now happening in my 1st tool invokation too. it says connector schema visible but callable function not present. can I please directly talk to someone at OpenAI? would love to debug this with them. this is extremely dissappointing for a company of this size to not get basic MCP integration right. even more so when official connectors like Canva and Notion work perfectlly.
