I have a question regarding functions, does it actually queue incoming requests when it's awakening from sleep?
Because I have a function that I send a fetch request to it from api, but if it was sleeping I will get this error:

request to http://function-bun.railway.internal:8080/api failed

it takes few seconds for it to completely awake, so the workaround I did was catching the error and recalling the fetch request again after 3 seconds.
But I'm trying to figure out if it should queue the incoming requests instead of the error I get, I mean is it a bug or just normal thing?
