Azure active directory Azure AD:MSAL-Cypress登录：ClientAuthError-base64字符串无效

正在尝试从Cypress执行静默登录。在本地存储中设置msal.client.info时，收到一个错误“Invalid base64 string”，并且它不是web应用程序的登录用户。试图通过导入@azure/MSAL browser添加MSAL.clientInfo。但是，没有运气。你能告诉我这里出了什么问题吗

import * as MSAL from "@azure/msal-browser"

Cypress.Commands.add("login", () => {
    cy.request({
      method: "POST",
      url: `https://login.microsoftonline.com/${Cypress.config("tenantId")}/oauth2/token`,
      form: true,
      body: {
        grant_type: "client_credentials",
        client_id: Cypress.config("clientId"),
        client_secret: Cypress.config("clientSecret"),
        resource: Cypress.config("resource")
      },
    }).then(response => {
      const MSALToken = response.body.access_token;
      const expiresOn = response.body.expires_on;
      console.log("Body: " + JSON.stringify(response.body));
      window.localStorage.setItem("msal.token.keys", `${Cypress.config("clientId")}|`);
      window.localStorage.setItem(`msal.access.token.key${Cypress.config("clientId")}`, MSALToken);
      window.localStorage.setItem(`msal.expiration.key${Cypress.config("clientId")}`, expiresOn);
      window.localStorage.setItem("msal.idtoken", MSALToken);
      window.localStorage.setItem(`msal.client.info`, MSAL.clientInfo);
    });
  });

收到的答复：

{
  "token_type": "Bearer",
  "expires_in": "3599",
  "ext_expires_in": "3599",
  "expires_on": "1622095375",
  "not_before": "1622091475",
  "resource": "00000002-0000-0000-c000-000000000000",
  "access_token": "eyJ0eXAiOiJKV1QiLCJh....BEFg"
}

设置时获取错误“无效的base64字符串”

window.localStorage.setItem(`msal.client.info`, MSAL.clientInfo);
