AWS EventBridge attach cross account policies multiple times

Question

I have a requirement such that the EventBridge in one account should accept events from multiple cross account event buses. It works fine with one policy as below:

new events.CfnEventBusPolicy(sourceBus, `CrossAccountPolicy${ACC_NAME}`, {
        action: "events:PutEvents",
        eventBusName: eventBusName,
        principal: ACC_NUMBER,
        statementId: `AcceptFrom${ACC_NUMBER}`,
      });

But when i try to attach multiple targets, it does not work as below:

targets.forEach((tempObj) => {
  new events.CfnEventBusPolicy(sourceBus, `CrossAccountPolicy${tempObj.ACC_NAME}`, {
    action: "events:PutEvents",
    eventBusName: sourceBus.eventBusName,
    principal: tempObj.ACC_NUMBER,
    statementId: `AcceptFrom${tempObj.ACC_NUMBER}`,
  });
})

Please note that I am using aws cdk to achieve this. Could anyone please let me know how to do this.

thanks

You can refer to the official doc. The definition of ** and * is in the data model doc[1]. The example usage of * and ** is in the DDL doc[2] and DML doc[3]. Since the timeseries is organized as a tree, * and ** is used to match all children node of one node. The difference is that * only matches one level and ** matches multi level nodes.
