InvalidIdentityPoolConfigurationException: Missing credentials in config

[lucascanavan]

Hi Danilo,

Nice repo! :)

However, I can't seem to get it working on my AWS account. I keep getting the following error even on the sigup page:

"InvalidIdentityPoolConfigurationException: Missing credentials in config"

http://lambdauth.lucas-canavan.net/signup.html

Any ideas???

Thanks,
Lucas

I noticed that the IAM roles associated with my Cognito identiy pool didn't look right so I updated the role associations to what I believe it's supposed to be be and it started working! :)

@lucascanavan could you tell me what the roles associated with my Cognito identiy pool are, and what were the updated you needed to do?

@lucascanavan I too would like to know how you were able to fix this as well, I am having the same issue

I ran into this recently, and for me (since this issue was at the top of my google search), the issue was that my assume role action was sts:AssumeRole when it needed to be sts:AssumeRoleWithWebIdentity. The error message was rather ambiguous.

I'm using AWS CDK, so what I ended up with looked like:

const authenticatedCognitoFederatedPrincipal = new iam.FederatedPrincipal("cognito-identity.amazonaws.com", {
    "StringEquals": {
        "cognito-identity.amazonaws.com:aud": identityPool.identityPoolId
    },
    "ForAnyValue:StringLike": {
        "cognito-identity.amazonaws.com:amr": "authenticated"
    }
}, "sts:AssumeRoleWithWebIdentity");

const unauthenticatedCognitoFederatedPrincipal = new iam.FederatedPrincipal("cognito-identity.amazonaws.com", {
    "StringEquals": {
        "cognito-identity.amazonaws.com:aud": identityPool.identityPoolId
    },
    "ForAnyValue:StringLike": {
        "cognito-identity.amazonaws.com:amr": "unauthenticated"
    }
}, "sts:AssumeRoleWithWebIdentity");
