Hey Everyone. (My first time posting here) I have a lambda on an EventBus that has to in turn invoke another lambda, but it seems like I have some kinda of permissions issue, as the second lambda never gets invoked. (Also no errors or logs in CloudWatch) If anyone has come across this issue before and have some links that I can read into to resolve the issue that would really be great. PS: Invoking the secondary lambda from a lambda attached to API Gateway works 100%

Hey @Theo Ferreira, welcome!

technically the endpoint call is made with postman to API Gateway, and API Gateway invokes a lambda, and then in turn invokes another lambda that does stuff (and that works), but if the initial lambda is attached to eventBus (and gets invoked by an event on EventBus) it does not invoke the secondary lambda

Got it!

export default {
  handler: `${__dirname.split(process.cwd())[1].substring(1).replace(/\\/g, '/')}/handler.main`,
  timeout: 900,
  events: [
    {
      eventBridge: {
        eventBus: "${self:provider.environment.RESOURCE_PREFIX}-${self:provider.environment.EVENT_BRIDGE_BUS}",
        pattern: {
          source: ['post.INSERT','post.MODIFY','post.REMOVE'],
        }
      }
    }
  ],
  iamRoleStatements: [ ... (permissions to invoke a lambda) ...],
};

is this what you meant ?

Oh this is a Serverless Framework project?

Yes

In the log of the first Lambda, can you enable the AWS SDK logging, and then see what the Lambda invoke call returns?

Sorry is this not the right workspace for this ? I thought that is what Serverless Stack is

Oh don’t worry man! I will help with whatever I can 🙂

Thanks @Frank I will try this in a little and see if I can see what the logs output

Awesome! Glad it’s working.
