Retell AI

<@605090813025976344> I am having an issue with a custom function. I am instructing the agent clearly to substitute the filter in the query params. At my endpoint i am receiveing {{phone_number}} instead of properly substituting the variable. ([v0] URL: api/find-patient?filter=%7B%7Bphone_number%7D%7D) this is how its being recieved. I have tried several different methods to get this working. This ussually is not an issue however at this point I am almost certain this is a retell issue. Can you or anyone please advise how to fix this? Oddly enough in the tool log it shows "tool invocation filter: '123456789' so in retell it appears as if its working. But whats actually being sent is not getting subsitituted with the correct variable. Any suggestions??
