Azure cosmosdb 宇宙图小精灵nodejs-未处理的承诺拒绝
我正在使用Azure cosmosdb 宇宙图小精灵nodejs-未处理的承诺拒绝,azure-cosmosdb,gremlin,graph-databases,azure-cosmosdb-gremlinapi,cosmos,Azure Cosmosdb,Gremlin,Graph Databases,Azure Cosmosdb Gremlinapi,Cosmos,我正在使用gremlin节点包向Azure cosmos graph db发送查询。对于正确的查询，它返回响应，但对于错误的查询，它会因错误而崩溃-未处理的承诺拒绝。我已经试过了，但还是没有成功 我的代码[不正确的查询]：- module.exports.getUserRole = async (event) => { console.log("In getUserRole"); return new Promise(async (resolve, reject
gremlinmodule.exports.getUserRole = async (event) => {
console.log("In getUserRole");
return new Promise(async (resolve, reject)=> {
try {
const { P, g, translator, client } = await cosmos.getGraphTraversalhelpers();
console.log("P", P);
console.log("graphTraversal", g);
console.log("translator", translator);
console.log("client._connection", client._connection);
console.log("client._connection.addListener", client._connection.on);
let query = g
.V()
.hasLabel("user")
.has("userName", event)
.has("status", P.neq("disabled"))
.out("hasUserRole")
.has("status", P.neq("disabled"))
.valueMap(true)
.getBytecode(); // prepares the query
client._connection.on('error', (error) => {
console.log('addListener', error);
reject(error);
})
let queryResult = await cosmos.executeQuery(translator.translate(query));
console.log("executeQuery is", query);
// driver.close(); // closes the db driver
if (Array.isArray(queryResult) && queryResult.length > 0) {
queryResult = queryResult[0];
}
return queryResult;
} catch (error) {
console.log("getUserRole cosmosgraph dao", error);
reject(error);
}
});

在WebSocket上。并抛出错误，但在上面的代码中从未调用我的捕获
备注：-以上代码在AWS lambda中运行未处理的异常与Gremlin库无关，而是我解析Gremlin响应的代码。我错误地解析了submit函数响应，导致代码因未处理的异常而崩溃
