[Azure Active Directory b2c] authentication failed due to: jwt audience is invalid

When I use the sample, all steps refer to this document.https://docs.microsoft.com/en-us/azure/active-directory-b2c/tutorial-single-page-app-webapi?tabs=app-reg-ga

An error occurred when I called the public API after logging in with my B2C account.

{"name":"AzureAD: Bearer Strategy","hostname":"jerry7","pid":1968,"level":30,"msg":"authentication failed due to: jwt audience is invalid","time":"2020-07-31T09:30:39.544Z","v":0}
GET /hello 401 5196.990 ms - -

This is the configuration of my web api sample.

const clientID = "9fe10508-405d-4617-8dee-52bca87e202f"; // Application (client) ID of your API's application registration
const b2cDomainHost = "poadevadb2c.b2clogin.com";
const tenantId = "poadevadb2c.onmicrosoft.com"; // Alternatively, you can use your Directory (tenant) ID (a GUID)
const policyName = "B2C_1_dpoa-b2c";

I’m sure all my Azure configurations are correct, but I can’t figure out where the problem is.

Hope to get help, thanks

I configured the application separately for the web api, but I did not use its client id correctly. thank you for your help
