Easily fix the AWS Cognito error message: Invalid identity pool configuration. Check assigned IAM roles for this pool.
The Error
{"__type":"InvalidIdentityPoolConfigurationException","message":"Invalid identity pool configuration. Check assigned IAM roles for this pool."}Fixes for Invalid identity pool configuration. Check assigned IAM roles for this pool.
This error is caused by IAM not being setup to trust the Cognito Identity pool.
First Fix: Add the Identity Pool to IAM Trust Relationships
Your IAM Role’s trust relationship should look something like the example one below, provided by AWS. It must have the principle specified as "Federated": "cognito-identity.amazonaws.com". This is the proper fix.
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "",
"Effect": "Allow",
"Principal": {
"Federated": "cognito-identity.amazonaws.com"
},
"Action": "sts:AssumeRoleWithWebIdentity",
"Condition": {
"StringEquals": {
"cognito-identity.amazonaws.com:aud": "us-east-1:12345678-corner-cafe-123456790ab"
},
"ForAnyValue:StringLike": {
"cognito-identity.amazonaws.com:amr": "unauthenticated"
}
}
}
]
}Seconds Fix – Temporary Workaround: Specify RoleARN and AccountID
This is not the recommended fix, but as a temporary work around you can specify the RoleARN and AccountID in the config
AWS.config.credentials = new AWS.CognitoIdentityCredentials({
IdentityPoolId: 'us-east-1:xxxxx-xxxx-xxxx-xxxx-xxxxx',
RoleArn: 'arn:aws:iam::xxxxx:role/Cognito_xxxxUsersUnauth_Role',
AccountId: 'xxxxxxxxx', // your AWS account ID
});
