Can anyon
I am encountering the same error, even tho I tried adding middleware for cryptoApi to the store.

adding two middleware keys is not the correct way to add the same for the cryptoNewsApi to do so you could have used another ,concat() method:

Can someone please help me with this error?

The particular lines above GIVING ERROR BELOW
