S3 failing to trigger aws lambda with no error - amazon-web-services

Question

Hi I want to trigger a lambda function from an s3 bucket on a any *.csv file upload.
My lambda works fine i can run it.
but seems like when i upload a csv to s3 the lambda is not triggered.
below is the code for my s3 bucket notification
resource "aws_s3_bucket" "myfirst-s3-bucket" {
bucket = "myfirst-s3-bucket"
}
resource "aws_s3_bucket_notification" "bucket_notification" {
bucket = "${aws_s3_bucket.myfirst-s3-bucket.id}"
lambda_function {
lambda_function_arn = "${aws_lambda_function.lambda.arn}"
events = ["s3:ObjectCreated:*"]
filter_suffix = ".jpg"
}
}
resource "aws_lambda_permission" "perme_bucket" {
statement_id = "AllowExecutionFromCloudWatch"
action = "lambda:InvokeFunction"
function_name = "${aws_lambda_function.lambda.arn}"
principal = "s3.amazonaws.com"
source_arn = "${aws_s3_bucket.myfirst-s3-bucket.arn}"
}

Answer 1

I think you should be using AllowExecutionFromS3Bucket and not AllowExecutionFromCloudWatch if you want to trigger it from S3 bucket.
Also the filter_suffix is for jpg and i think you want .csv
Please find the code on github that will be helpful github code
resource "aws_lambda_permission" "perme_bucket" {
statement_id = "AllowExecutionFromS3Bucket"
action = "lambda:InvokeFunction"
function_name = "${aws_lambda_function.lambda.arn}"
principal = "s3.amazonaws.com"
source_arn = "${aws_s3_bucket.myfirst-s3-bucket.arn}"
}
