Credential Manager Throws Error: 'JSON Object doesn't have linked key' When Creating Credential

Question

I can successfully created a passkey device in Google and created a credential (screen lock) which can be seen in "Password Manager" in "Manage your Google Account" before. And then I did some changes and tests. And I rolled back my code.

I can get the passkey prompt like this

However, App cannot show credential selector and got the following error:

And this is my assetlinks.json:

[
    {
        "relation": [
            "delegate_permission/common.handle_all_urls",
            "delegate_permission/common.get_login_creds"
        ],
        "target": {
            "namespace": "web",
            "site": "https://myapp.test.com"
        }
    },
    {
        "relation": [
            "delegate_permission/common.handle_all_urls",
            "delegate_permission/common.get_login_creds"
        ],
        "target": {
            "namespace": "android_app",
            "package_name": "com.myapp.test",
            "sha256_cert_fingerprints": [
                "62:8D:D4:12:94..."
            ]
        }
    }
]

Well, I know that JSON Object doesn't have linked key usually means that I didn't setup assetlinks.json well on my site. And I also read the answer of the question Android FIDO2 throwing vague errors

However, I can reach my assetlinks.json content throw the link https://myapp.test.com/.well-known/assetlinks.json (This link is fake, not actual one), and I can open my app through app links. And, I can successfully created a passkey device in Google before. But now CredentialManager.create(context).createCredential(context, request) does not work any more
