Cyclic dependency with json feature and oauth2 crate

[Mautriz]

I have the crates oauth2 (v4.1.0) and sqlx[json] (v0.5.5):

[dependencies]
oauth2 = "4.1.0"
sqlx = { version = "0.5.5", features = ["json"] }

When attempting to build, I am getting the following error:

error: cyclic package dependency: package `ahash v0.7.4` depends on itself. Cycle:
package `ahash v0.7.4`
    ... which is depended on by `hashbrown v0.11.2`
    ... which is depended on by `indexmap v1.7.0`
    ... which is depended on by `serde_json v1.0.64`
    ... which is depended on by `wasm-bindgen v0.2.74`
    ... which is depended on by `js-sys v0.3.51`
    ... which is depended on by `getrandom v0.2.3`
    ... which is depended on by `ahash v0.7.4`

This only happens when I activate the json feature flag on sqlx. What is the problems here ? How do I understand it? Are there any workarounds to make these libs/features work together? What are the alternatives?

This is discussed in detail here: tkaitchuck/aHash#95

Tldr, activate the new feature resolver in Cargo (to be default in edition 2021): https://doc.rust-lang.org/cargo/reference/features.html#feature-resolver-version-2

Thank you a lot !

resolver version 2 is not enough when using the json feature. As per tkaitchuck/aHash#95 (comment), only sqlx 0.5.7 works
