i'm trying to create a AWS cognito login with fb. the proble is it is throwing error from this API ( https://cognito-identity.us-east-1.amazonaws.com/ --> 400 error) like:
{
"__type": "InvalidIdentityPoolConfigurationException",
"message": "Invalid identity pool configuration. Check assigned IAM roles for this pool."
}
how to rectify it as resources are low in the internet for this error.
