这个错误是由于引号未经过处理，在代码中夹杂了一个字符转义符“&”，导致出现了错误。要解决这个问题，可以将代码中的“&”替换为“&”，或者使用字符串拼接的方式将引号换成转义符。具体代码示例如下：

代码示例一：

"authentication": {
  "type": "ActiveDirectoryOAuth",
  "parameter": {
    "clientId": "yourClientId",
    "clientSecret": "yourClientSecret",
    "resource": "https://management.core.windows.net/",
    "tenantId": "yourTenantId",
    "grantType": "client_credentials"
  }
}

代码示例二：

"authentication": {
  "type": "ActiveDirectoryOAuth",
  "parameter": {
    "clientId": "yourClientId",
    "clientSecret": "yourClientSecret",
    "resource": "https://management.core.windows.net/",
    "tenantId": "yourTenantId",
    "grantType": "client_credentials"
  }
}
