Here is the error I am seeing:
type mismatch resolving <sp_core::sr25519::Public as IdentifyAccount>::AccountId == u64
--> pallets/src/mock.rs:76:2
|
76 | type Public = <Signature as Verify>::Signer;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected u64, found struct
It seems you have a type mis-configuration here. As the compiler is hinting at you, in one place, you have said that the AccountId type should be u64, whereas somewhere else, you are using a more complex signature structure.
You must pick and use just one of these types for your AccountId.
If you want to use a u64, I suggest you look at the simple mock.rs file generated for the substrate-node-template example:
https://github.com/paritytech/substrate/blob/master/bin/node-template/pallets/template/src/mock.rs
If you want to use a more complex public key for the AccountId, you can look at the parallel example:
