AmazonCloudWatchLogsClient.ListAnomaliesAsync throws Amazon.Runtime.AmazonClientException: We expected a VALUE token but got: ObjectStart about aws-sdk-net HOT 14 OPEN

@danispir Thanks for the bigger snippet. The logSamples is coming back different then the .NET SDK is expecting. I have a query to the CloudWatch Logs team going on to understand why that is.

from aws-sdk-net.

Do you see the same error when using the AWS CLI? For example: aws logs list-anomalies --anomaly-detector-arn "serverArn". Our CloudWatch Logs client is generated, we don't modify the response that's coming from the service.

from aws-sdk-net.

Hi @dscpinheiro. Thanks for your reply.
I tried, but the method list-anomalies is not available at all. Error aws: error: argument operation: Invalid choice
I also tried it with Python Boto3 and I'm getting the message list_anomalies attribute does not exists. Although it is available in their documentation.

My assumption is that this method has been hidden entirely?

from aws-sdk-net.

No, the API is public but it was released recently, during last year's re:Invent: https://github.com/aws/aws-sdk-net/blob/main/changelogs/SDK.CHANGELOG.2023.md#376930-2023-11-27-0424-utc.

It's available in the last version of the CLI, so you may have to update your version:

PS> aws --version
aws-cli/2.15.24 Python/3.11.6 Windows/10 exe/AMD64 prompt/off

PS> aws logs list-anomalies
{
    "anomalies": []
}

from aws-sdk-net.

You were right. Now I can execute correctly aws logs list-anomalies command.

But from AWSSDK.NET in my .net 8 console app, I'm still getting same error. Any idea?

from aws-sdk-net.

@danispir Can you enable response logging by adding the following code at the startup of your test application and share the response JSON from the call. Be sure to redact anything sensitive in the response.

AWSConfigs.LoggingConfig.LogTo = LoggingOptions.Console;
AWSConfigs.LoggingConfig.LogResponses = ResponseLoggingOption.Always;

from aws-sdk-net.

Hello @normj. Below is the output I get. Since it seems that I do get the response, could be a deserialization issue when trying to deserialize LogSamples array of objects?

@danispir Thanks for the log. Unfortunately it cut off the response payload at 1K and I think we are missing the part that the unmarshaller is having a problem. Can you add the following line increase the size of the response payload logging?

AWSConfigs.LoggingConfig.LogResponsesSizeLimit = 10485760;

from aws-sdk-net.

I increased it to 20_000_000.
