No apis published, showing too many error in console after login

[ravineshappypie]

Hi

I deployed in us-east-1 reason, Front page is working fine.
But after login, I am not able to see any API, while I have putted the api.

In console many error is showing like:

I did some changes in "dev-portal-DevPortalLambdaFunction-fVvFzmSMwWTL" lambda function by assumption it may be CORS issue.

replaced app.use(cors())

By

app.use(cors({
origin: '', // Allow any origin
methods: 'OPTIONS,POST,GET',
allowedHeaders: 'Content-Type'
}));
app.options('', cors()); // Enable preflight requests for all routes

But still getting the issue. Please provide some resolution on this.
