multi signature – My sortedmulti_a taproot descriptor is being rejected by bitcoin-cli, why?

I’m trying the next on regtest:

request: ["id": "51C82AC3-C966-4B37-BF01-426AB6A822D4", "jsonrpc": "1.0", "method": "getdescriptorinfo", "params": ["descriptor": "tr(sortedmulti_a(2,[38358b48/48h/1h/0h/3h]tpubDEJEvCnT3zY8LiJLXijiWFMT47h5Qz5xgbTx3ZrzyEtv9SSbFUKHQHk7mYPA1XezsRQwxm3DX12B8Sy47dnUhYLnF6HnU7nCkdgvxxBxkV7/0/*,[5f8ca6c0/48h/1h/0h/3h]tpubDEY9RgKWR6YkqvniTF29GSgocQiPmHQrmYxhFQ8PwApidoyJSffSSHUMekMggsPMVNGpiqx1A2KMf9hetZ5G5nrW9DbspqqMdg8bTaEGGBA/0/*))"]]
json: {
    error =     {
        code = "-5";
        message = "tr(): A number of ']' characters discovered for a single pubkey";
    };
    id = "51C82AC3-C966-4B37-BF01-426AB6A822D4";
    outcome = "";
}

In bitcoin/docs/Descriptors.md I do not see something mentioning why my descriptor could be invalid, may you please let me know what I’m doing unsuitable?
