Obscure error when aws kinesis firehose delivery stream s3 buffer interval is too low

[jleclanche]

I tried setting up a aws_kinesis_firehose_delivery_stream and set s3_configuration.buffer_interval to 30. This is below the minimum which is 60. I was greeted by this super unhelpful error:

* aws_kinesis_firehose_delivery_stream.deck_archetype_log_stream: 1 error(s) occurred:

* aws_kinesis_firehose_delivery_stream.deck_archetype_log_stream: [WARN] Error creating Kinesis Firehose Delivery Stream: "1 validation error(s) found.", code: "InvalidParameter"

It took me a while to figure out that the problem was with the buffer interval. I don't know if the problem is in terraform or AWS, but it'd be nice to check for the minimum at plan time either way.

+1 It gives a similar error when password field size is less than 6. Interestingly, updating the stream gives proper error:

* aws_kinesis_firehose_delivery_stream.kinesis_firehose_redshift: Error Updating Kinesis Firehose Delivery Stream: "test_stream"
InvalidParameter: 1 validation error(s) found.
- minimum field size of 6, UpdateDestinationInput.RedshiftDestinationUpdate.Password.
