Error when using sqlx postgres with axum-login

[martinrlilja]

I'm not sure where is the best place for this issue.

I followed the sqlite example from axum-login, but replaced sqlite with tower-sessions-sqlx-store and postgres.

However I get this error when navigating to any page after sign in:

axum_login::service: could not create auth session from session err=invalid type: sequence, expected u8

I think it comes from the message pack decode, because when I run the session data in the database through online message pack decoders the auth_hash in axum-login.data is an array of arrays with a single number inside.

This is an example of the raw data in the database:

93c410030238e6944411151b0337b899fb099e81af6178756d2d6c6f67696e2e6461746182a9617574685f68617368dc001091a2313991a331303591a2363091a2383591a331323491a331353891a2373391a331323991a331363391a331303991a2383291a2353391a2323091a2353991a332343091a3313137a7757365725f6964d92431333639336335352d376339652d343938312d613336642d35323335313433626630373599cd07e8cd0111143a0dce35585b1a000000

Which gets decoded as:

[
  "AwI45pREERUbAze4mfsJng==",
  {
    "axum-login.data": {
      "auth_hash": [
        [
          "19"
        ],
        [
          "105"
        ],
        [
          "60"
        ]
...
    ]
  }
]

Switching from tower-sessions-sqlx-store to the built in MemoryStore fixes the problem.

Edit: swapping out rmp-serde for serde_json also fixes the problem. Sadly flexbuffers doesn't support i128.
