AWS multiple dynamic blocks in teraform aws_s3_bucket_notification

I am trying to get work s3 notifications with dynamic blocks in terraform. One of them should to be lambda and the second one must to be SQS.

For now I have code like this and it doesn't work.

I am getting this kind of error:

Error: Unsupported attribute
  on triggers.tf line 51, in resource "aws_s3_bucket_notification" "s3_lambda_sqs_trigger":
  51:       prefix = i.queue_prefix
This object does not have an attribute named "queue_prefix".

Is possible to have 2 dynamic blocks for one s3 bucket, please?

Could you help me, please?

Thanks in advance.

      events = item.events

      events              = lambda_function.value.events

      filter_prefix       = queue.value.prefix
    }
  }    
}

Here is the error message:

> prefix = i.queue_prefix
This object does not have an attribute named "queue_prefix".

So let's take that error message and look at the code:

for i in each.value.queue: {
      prefix = i.queue_prefix
      events = i.events
    }

So you are trying to reference an attribute named queue_prefix there, but if you look at the objects you are iterating over:

queue = [
            {
                events          = ["s3:ObjectCreated:*"]
                name            = "filter5"
                filter_prefix   = "appointment/status/"
            },
            {
                events          = ["s3:ObjectCreated:*"]
                name            = "filter6"
                filter_prefix   = "operator/status/"
            },
            {
                events          = ["s3:ObjectCreated:*"]
                name            = "filter7"
                filter_prefix   = "team/status/"
            },
            {
                events          = ["s3:ObjectCreated:*"]
                name            = "filter8"
                filter_prefix   = "sa/status/"
            }
        ]

There is nothing named queue_prefix. Exactly as the error message is telling you. There is however an attribute named filter_prefix which is almost certainly what you are trying to reference. So you need to change your code to this:

for i in each.value.queue: {
      prefix = i.filter_prefix
      events = i.events
    }
