AWS CLI error: Member must satisfy regular expression pattern

0

Hello,

i'm on this issue since yesterday without any means to understand what's going wrong.
I install awscli via pip, setup my credentials, and now i'm able to retrieve my the whole list of logs hosted on Cloudwatch:

        {
            "arn": "arn:aws:logs:eu-west-1:077720739816:log-group:testloginstance:*",
            "creationTime": 1563357673443,
            "metricFilterCount": 0,
            "logGroupName": "testloginstance",
            "storedBytes": 129594
        },

But when i try to display logs, i always have the same error:
An error occurred (InvalidParameterException) when calling the GetLogEvents operation: 1 validation error detected: Value 'log-group:testloginstance' at 'logStreamName' failed to satisfy constraint: Member must satisfy regular expression pattern

Here my command and debug output:

aws logs --debug get-log-events --log-group-name testloginstance --log-stream-name log-group:testloginstance

I especially try to take a simple log ressource name, without special characters, trying several syntax, same result or API response that this log doesn't exist.

Any help would be greatly appreciated.

Thx

Hi,
Change your invocation
From:

aws logs get-log-events --log-group-name testloginstance --log-stream-name log-group:testloginstance

To:

aws logs get-log-events --log-group-name testloginstance --log-stream-name testloginstance

FYI: I was able to reproduce the same error.

C:\Users\randy\aws\sam\projects\nodejs>aws logs get-log-events --log-group-name CloudWatchLogGroup --log-stream-name log-group::MyLogStream

An error occurred (InvalidParameterException) when calling the GetLogEvents operation: 1 validation error detected: Value 'log-group::MyLogStream' at 'logStreamName' failed to satisfy constraint: Member must satisfy regular expression pattern: [^:*]*

And after I fixed the --log-stream-name

C:\Users\randy\aws\sam\projects\nodejs>aws logs get-log-events --log-group-name CloudWatchLogGroup --log-stream-name MyLogStream
{
    "events": [
        {
            "timestamp": 1566284476276,
            "message": "[System] [Information] [7036] [Service Control Manager] [EC2AMAZ-7JBQ892] [The Microsoft Account Sign-in Assistant service entered the stopped state.]",
            "ingestionTime": 1566284525380
        },

Hope this helps!
