There was a problem hiding this comment.
every message that comes in you generate an array of all the values in the enum. How about renaming the enum values so they are lowercase and you can do !!MsgType[msg[0][0]]?

Ah yes you’re right. Hmm, the tricky part is that some of the enum values can’t be valid enum keys, like graph-url. We could generate the array once outside of the function. I’m not sure what a better solution could be, what do you think?

What is it?
Description
fixes: #6921
If an unknown message is sent to the SW which isn't an array, Qwik throws an error attempting to slice the array. If it is an array type, Qwik will log an error. This PR will check if messages are Qwik messages before queuing them and ignore unknown messages.
