Raising event from consumer function of aws-lambda-sqs-lambda

[dextel2]

Currently I am trying to raise an event from @aws-solutions-constructs/aws-lambda-sqs-lambda:

Here is a boilerplate of my approach infra.ts

        const fanout = new LambdaToSqsToLambda(stackScope, "LambdaToSqsToLambda", {
            producerLambdaFunctionProps: {
                runtime: lambda.Runtime.NODEJS_14_X,
                handler: "index.queueRecordsFunction",
                code: lambda.Code.fromAsset(`../dist`),
              
            },
            consumerLambdaFunctionProps: {
                runtime: lambda.Runtime.NODEJS_14_X,
                handler: "index.processRecordFunction",
                code: lambda.Code.fromAsset(`../dist`),
            },
        });

I am getting the event bridge event bust from the bus name i.e.

const eventBus = events.EventBus.fromEventBusName(this, "Id", props.connectEventBusName);

I have added Rule and addTarget as well.

and eventBus.grantPutEventsTo(fanout.consumerLambdaFunction);, I am still getting AccessDeniedException and the error message states that I am using the 'default' bus but I am accessing my own bus.

.....is not authorized to perform: events:PutEvents on resource: arn:aws:events:us-west-2:035996677488:event-bus/default because no identity-based policy allows the events:PutEvents action"

What am I doing wrong here ?
