You might need to also specify

peerOwnerId

on the

VpcPeeringConnection

. Here's an example from a config I know works:

const peering = new aws.ec2.VpcPeeringConnection(`${this.name}-peer-to-${peerName}`, {
    vpcId: this.vpc.id,
    peerVpcId: args.peerVpc.vpc.id,
    peerOwnerId: peerOwner,
    autoAccept: true,
    accepter: {
        allowRemoteVpcDnsResolution: true,
    },
    tags: {
        ...this.baseTags,
        Name: args.nameTag,
    },
});

Thanks!
