rdsclient: createDBInstanceReadReplica always pass "preSignedUrl", which causing InvalidParameterCombination error

[richqi]

I received this error when using sdk:
InvalidParameterCombination (client): Your request does not require the preSignedUrl parameter. Please remove the preSignedUrl parameter and try your request again.

preSignedUrl is auto generated by the sdk, regardless of passing "SourceRegion" or not. So there is no way to remove it.

Can you please post a code sample that is triggering this issue for you? Can you also please provide the version of the SDK you're using?

SDK version: 3.36.15

Sample Code:

$rdsClient = new RdsClient([
                'region' => 'us-west-2',
                'version' => 'latest',
                'credentials' => [
                    'key' => 'xxx',
                    'secret' => 'xxx',
                ],
 ]);

try {
    $result = $rdsClient->createDBInstanceReadReplica([
        'AutoMinorVersionUpgrade' => 1,
        'AvailabilityZone' => 'us-west-2a',
        'CopyTagsToSnapshot' => 0,
        'DBInstanceClass' => 'db.t2.micro',
        'DBInstanceIdentifier' => 'test-db-1-rr', // REQUIRED
        'EnableIAMDatabaseAuthentication' => 0,
        'PubliclyAccessible' => 0,
        'SourceDBInstanceIdentifier' => 'test-db-1-rw', // REQUIRED
        'StorageType' => 'standard',
    ]);

    return $result;
} catch (\Exception $e) {
    return $e->getMessage();
}

I removed "CreateDBInstanceReadReplica" from PresignUrlMiddleware::wrap in RdsClient.php to make it work.

Thanks for the report @richqi, I've marked this as a bug and we'll work on a fix.
