Shouldn't we be able to provide a String so that we can use placeholders? In this case the issue is in the yaml schema.

I don't think we want all the properties to be String in the schema itself. No matter how it's brought including with property placeholder, if at runtime it's finally a number, then schema should declare it's a number. The property placeholder is some magic beyond that I would say.

Considering the purpose of the schema is to express to the user what can be written there, I believe the schema should allow for string types there. At the same time, considering that we can use placeholders almost everywhere, it's very likely all properties will be string 😅.

I want to propose that when writing a number over a number field, make Kaoto understand it and write as-is, otherwise, write the string.

For now we're going with serializing a number when is a number, in case of a placeholder, we serialize string.
