Description

When trying to call the module with the specification of a Capacity Reservation ID, the module ends up with the following error:


│ Error: Invalid function argument

│ on .terraform/modules/terraform-aws-ec2-instance/main.tf line 45, in resource "aws_instance" "this":
│ 45: capacity_reservation_id = lookup(capacity_reservation_target.value, "capacity_reservation_id", null)
│ ├────────────────
│ │ capacity_reservation_target.value is "cr-xxxxxxxx"

│ Invalid value for "inputMap" parameter: lookup() requires a map as the
│ first argument.

As per line 45 analysis, it looks like the bug is in the following statement:

capacity_reservation_id = lookup(capacity_reservation_target.value, "capacity_reservation_id", null)

it should rather be as follows:

capacity_reservation_id = lookup(capacity_reservation_target, "capacity_reservation_id", null)

In this case, terraform should lookup in the capacity reservation target map (since it is the iterator in the for_each) rather than in its value for the mapping of the attribute capacity reservation id

Motivation and Context

Fixes #277

Breaking Changes

No breaking changes, just fixing a typo in line 45 in the main.tf

How Has This Been Tested?

  • I have updated at least one of the examples/* to demonstrate and validate my change(s)
  • I have tested and validated these changes using one or more of the provided examples/* projects
    This fix is hard to test since it requires to have an ongoing capacity reservation which is released by AWS.
    In order to test this, I stopped at the plan stage.
  • I have executed pre-commit run -a on my pull request

We shouldn't be deleting the README documentation - not sure why our checks are still passing with all this being deleted. Please update when you get a chance

@bryantbiggs thanks for your feedback.

this was due to the fact that I mistakenly removed the end of tfdocs hook in the complete example README:

Now pre-commit hooks run correctly.
