Bedrock Agent and Bedrock Agent Runtime do not use service specific endpoint overrides environment variables

[nateglims]

Describe the bug

When setting AWS_ENDPOINT_URL_BEDROCK_AGENT and/or AWS_ENDPOINT_URL_BEDROCK_AGENT_RUNTIME, the SDK continues using the default endpoint for the Bedrock Agent services. I have not tested other aws-sdk-rust crates.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

Using these env vars should override the endpoint used.

Current Behavior

The default endpoint is used.

Reproduction Steps

Set the variables:

export AWS_ENDPOINT_URL_BEDROCK_AGENT=https://localhost:8080/
export AWS_ENDPOINT_URL_BEDROCK_AGENT_RUNTIME=https://localhost:8080/

Configure the SDK without overriding the endpoint.

To show endpoint resolution, run with RUST_LOG="info,aws_smithy_runtime::client::orchestrator::endpoints=debug" cargo run

Crate attached.

Possible Solution

No response

Additional Information/Context

• AWS_ENDPOINT_URL does override.
• The AWS CLI and Boto3 both override as expected.

The Rust SDK currently does not support setting service-specific endpoints via environment variables. We do support other programmatic ways of setting explicit endpoints which are documented here https://docs.aws.amazon.com/sdk-for-rust/latest/dg/endpoints.html

Edit: Ignore my previous message, I shouldn't be responding to issues that late at night. We should actually support this via this piece of generated code:

aws-sdk-rust/sdk/bedrock/src/config.rs

Lines 1289 to 1296 in ab2478c

	fn service_config_key<'a>(env: &'a str, profile: &'a str) -> aws_types::service_config::ServiceConfigKey<'a> {
	::aws_types::service_config::ServiceConfigKey::builder()
	.service_id("bedrock")
	.env(env)
	.profile(profile)
	.build()
	.expect("all field sets explicitly, can't fail")
	}

If this isn't working it is a bug.

Thanks. FYI Bedrock is a distinct service from bedrock agents. I'm not sure if that one also has this problem.
