nxdomain errror when using AWS.Location.search_place_index_for_text

[shirawebill]

The code in AWS.Request.build_host 1 (https://github.com/aws-beam/aws-elixir/blob/v0.12.0/lib/aws/request.ex#L165)
will produce a hostname like:
geo.eu-west-1.amazonaws.com
for these requests, but that host doesn’t exist

The Amazon documentation (https://docs.aws.amazon.com/location/latest/developerguide/location-regions.html)
says that the correct host for a place search in eu-west-1 is:
places.geo.eu-west-1.amazonaws.com,
which does resolve to an address.

My code:

client = AWS.Client.create(System.fetch_env!("AWS_ACCESS_KEY_ID"), System.fetch_env!
("AWS_SECRET_ACCESS_KEY"), "eu-west-1")

AWS.Location.search_place_index_for_text(client, "site_addresses", %{"Text" => "2 Water Lane"})

Response:

{:error, :nxdomain}

Hi @shirawebill 👋
I'm going to take a look. This is probably something we are missing in the generator (aws-codegen).

@shirawebill would you mind to try with the version from this branch => ps-add-host-prefix-to-request ?

{:aws, github: "aws-beam/aws-elixir", branch: "ps-add-host-prefix-to-request"}

It should be fixed now.

[philss]

If this passes for you, I should release a version with the fix.

Hi @philss
Thank you so much.

It does work for me; please see the below response:

Cool!
I should probably release a new version with this later today.
I will let you know :)
