Batch Size / Interval not working if BatchSize items >2 (HTTP Request Node)

[maxmarines]

Describe the bug Batch Size / Interval not working if BatchSize items >2 in HTTP Request node.

To Reproduce Steps to reproduce the behavior:

1. Go to 'HTTP Request'
2. Set 'Batch Interval:2000'
3. Set 'Batch Size:5'
4. See error - delay ( Batch Interval) only between the first and second request. (2,3,4,5 requests are sent simultaneously )

Expected behavior Batch Interval between all 5 requests.

Environment (please complete the following information):

• OS: [e.g. Ubuntu 20 LTS]
• n8n (0.100.0)
• Node.js Version form dockerhub

for test localhost please go to https://webhook.site/ , copy your unique URL and set in URL in HTTP Request2 (last node in workflow).

@maxmarines Had a quick look and this does not seem to be a bug. Just remove the split batches node and it should work as expected. The split batches node is not needed. the HTPP will iterate automatically over all items. Can you please confirm that it solves the issue? Thanks.

@RicardoE105 Thank you, your advice partially worked. When checking, it turned out that this function works only if the BatchSize >=2. Set Batch Size value to -1/0/1 does not allow you to send requests one at a time and all requests are sent together, with no set delay.
