Error when using with Zed

[zaucy]

failed to deserialize response from language server: invalid type: string "workspaceFolders", expected struct WorkspaceFoldersServerCapabilities at line 1 column 97. response from language server: "{\"capabilities\":{\"textDocumentSync\":{\"change\":1,\"openClose\":true},\"workspace\":[\"workspaceFolders\",{\"changeNotifications\":true,\"supported\":true}]},\"serverInfo\":{\"name\":\"ecsact_lsp_server\",\"version\":\"0.1.0\"}}"

{
    "capabilities": {
        "textDocumentSync": {
            "change": 1,
            "openClose": true
        },
        "workspace": [
            "workspaceFolders",
            {
                "changeNotifications": true,
                "supported": true
            }
        ]
    },
    "serverInfo": {
        "name": "ecsact_lsp_server",
        "version": "0.1.0"
    }
}

pretty sure that shoudl be an array of objects, not an array.
