error[E0308]****: mismatched types

= note: MiniSecretKey and MiniSecretKey have similar names, but are actually distinct types

note: MiniSecretKey is defined in crate schnorrkel

= note: perhaps two different versions of crate schnorrkel are being used?

Compiling parity-util-mem-derive v0.1.0

Compiling sp-storage v4.0.0

Compiling parking_lot v0.11.2

Compiling const-oid v0.9.6

You use 2 different versions of schnorrkel 0.11.4 and 0.9.1 and try to use objects from one version with functions from another version. this doesnt work.

You should find out which of your dependencies import the different versions (look at cargo tree). then you can figure out which one to change and to which version.

I also update the cargo.toml file to:
[package]

name = "pallet_ideas"

version = "0.1.0"

edition = "2021"

[dependencies]

schnorrkel = { version = "0.11.4", optional = true }

frame-support = { version = "4.0.0", default-features = false, features = ["std"] }

frame-system = { version = "4.0.0", default-features = false, features = ["std"] }

sp-runtime = { version = "4.0.0", default-features = false, features = ["std"] }

sp-std = { version = "4.0.0", default-features = false, features = ["std"] }

[workspace.dependencies]

schnorrkel = "0.11.4"

[lib]

name = "pallet_ideas"

path = "src/lib.rs"

but the issue persist. Do you have any idea how to solve it?

Please format your code (and errors, and toml files) according to the pinned topic - it's barely readable now and probably missing some of the info to formatting.

There is also information missing from your tree. That is only helpful if you see which crates are pulling in the different versions, so you need the full output (not filtered to the schnorrkel lines)
