go to post Theo Stolker · Jul 8, 2022 Hi @Lorenzo, Thanks for the great tool! I tried generating a Fitbit client based on https://dev.fitbit.com/build/reference/web-api/explore/fitbit-web-api-sw..., but it failed, because parameter names have "-" characters, and these cannot be part of a Property name. Therefore I extended the name() Class method to also have the "-": ClassMethod name(name As %String) As %String [ CodeMode = expression ] { $Translate(name, "$_-","") } The proxy generation still fails, and given that I don't use that right now, I have disabled that. With these changes everything works great!
