(aws-events-targets) Lambda function as event target for conditional event rule doesn't work

[rehos]

We are using LambdaFunction as an event target on an event rule for which we set a condtion. It looks like the auto generated lambda permission doesn't "inherit" the condition from the rule. This results in the following cloudformation error during deployment:

Template format error: Unresolved resource dependencies [MyRuleABCD1234] in the Resources block of the template (Service: AmazonCloudFormation; Status Code: 400; Error Code: ValidationError; Request ID: .....; Proxy: null)

It can be reproduces with the following code:

        const myRule = new Rule(this, 'MyRule', {
            ruleName: 'MyRule',
            schedule: Schedule.cron({
                minute: '00',
                hour: '22',
                day: '*',
                month: '*',
                year: '*',
            }),
            targets: [
                new LambdaFunction(
                    myLambdaFunctionAliasArn,
                    {
                        retryAttempts: 3,
                        maxEventAge: Duration.hours(2),
                    }
                ),
            ],
        });

        (myRule.node.defaultChild as CfnRule).cfnOptions.condition = new CfnCondition(this, 'MyCondition', ....);

Is there anyway to workaround this issue or should a report a bug?

To answer my own question for anyone who lands here: A workaround is to use aspects as suggested here.
