从 gremlin 控制台连接到 cosmos db graph api："exception=Keys must be scalars"

Question

我正在尝试通过 gremlin 控制台 3.3.4 连接到 cosmos db，之后 remote_secure.yaml 如下：

hosts: [*****.gremlin.cosmosdb.azure.com]
port: 443
username: /dbs/sample-database/colls/sample-collection
password: ******
connectionPool: {
  enableSsl: true}
{ className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0, config: { serializeResultToString: true }}:

但是当我运行:remote connect tinkerpop.server conf/remote-secure.yaml

我收到以下错误

==>Error during 'connect' - Can't construct a java object 
for tag:yaml.org,2002:org.apache.tinkerpop.gremlin.driver.Settings;
exception=Keys must be scalars but found:

知道我做错了什么吗？

看起来你的配置有问题。您在最后一行缺少 serializer 键：

hosts: [*****.gremlin.cosmosdb.azure.com]
port: 443
username: /dbs/sample-database/colls/sample-collection
password: ******
connectionPool: {
  enableSsl: true}
serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0, config: { serializeResultToString: true }}

从 gremlin 控制台连接到 cosmos db graph api："exception=Keys must be scalars"

connecting to cosmos db graph api from gremlin console: "exception=Keys must be scalars"
