When I started webase-node-manager and entered the url "http://x.x.x.x:5001/WeBASE-Node-Manager/login" in the browser, a problem occurred: {"code":202052,"message":"invalid token","data":null,"attachment":null}. Is my configuration wrong?

按照文档https://webasedoc.readthedocs.io/zh_CN/latest/docs/WeBASE-Install/developer.html启动WeBASE-Front报错
Failed to connect to nodes: [ ssl handshake failed:/127.0.0.1:20200, The reasons for failure may be: 1. the configured certificate is not the same set of certificates as the node's certificate; 2. the configured certificate is not issued by the same authority as the node's certificate. Please refer to https://fisco-bcos-documentation.readthedocs.io/zh_CN/latest/docs/sdk/java_sdk.html#id24]

反复确认了，证书没错啊。从sdk目录下拷贝过来的

位置：https://webasedoc.readthedocs.io/zh_CN/latest/docs/WeBASE-Sign/interfaces.html#id51
说明：导入私钥接口的example，json格式不对，privateKey字段后边少了个逗号。
疑问：请问这个私钥内容是什么格式的，明文十进制字符串 or 十六进制字符串 or bytes？

After downloading and configuring according to the document, start it and print the error log with the following problems:
