AWS SDK 抛出 SdkClientException

Question

I am attempting to retrieve a secret from aws secrets manager. My application can retrieve 3 / 4 secrets. When attempting to retrieve the 2nd secret, i get an interrupt exception. The code below is what i am using. I am unsure where to look or why this is happening. It consistently happens when attempting to retrieve the 2nd secret. I have verified that it exists in aws and that it contains the value i expect.

I am using the reativerse [https://github.com/reactiverse/aws-sdk] library in tandem with vert.x + aws sdk 2. Any help or pointers on where to look would be greatly appreciated. The exception i see and the code i have are written below.

private final SecretsManagerAsyncClient client = VertxSdkClient.withVertx(SecretsManagerAsyncClient.builder(), ctx).build();

public <T> Promise<T> getSecret(String secretName) {
    Promise<T> completableFuture = Promise.promise();

    Context ctx = Vertx.vertx().getOrCreateContext();

Answer 1

See SdkInterruptedException ...it has one method getResponse() :

try {

    // provoke the exception in here

} catch (SdkInterruptedException e) {
    System.err.println(e.getResponse());
}

This should (hopefully) at least tell why the request had been interrupted.
// log exception. is not the correct approach to handle any Exception .

The SdkClientException might be more relevant than the SdkInterruptedException :

try { ...
} catch (SdkClientException e) {
    // log that exception, instead of ignoring it.
    System.err.println(e.getMessage());
}

This is how an Authorization Header (AWS Signature Version 4) should basically look alike. It may well be, that HMAC-SHA256 headers are being enforced (they're different on each single request). I could even provide a known to be working example ... which would show how to configure the SecretsManagerClient . I'd suspect the root cause related to that client's configuration.

When I read "when attempting to retrieve the 2nd secret", this with high probability means that you need a refresh the HMAC-SHA256 signature before the second request will be performed. Destroying the client and constructing it again may be one sloppy workaround. When seeing duplicate values for AWS4-HMAC-SHA256 header on both requests, this definitely is the cause.
