Hi guys, we are struggling to connect to kinesis when mfa is activated. I did configured everything according to the documentation but still getting exception :
val producerConfig = new Properties() producerConfig.put(AWSConfigConstants.AWS_REGION, awsRegion) producerConfig.put(AWSConfigConstants.AWS_ACCESS_KEY_ID, awsAccessKey) producerConfig.put(AWSConfigConstants.AWS_SECRET_ACCESS_KEY, awsSecretAccessKey) producerConfig.put(com.amazonaws.auth.profile.internal.ProfileKeyConstants.AWS_SESSION_TOKEN, awsSessionToken) with a very simple pipeline : val producer = new FlinkKinesisProducer(new SimpleStringSchema(), producerConfig) producer.setFailOnError(true) producer.setDefaultStream(outputStreamName) producer.setDefaultPartition("0") env.fromElements("a", "b", "c").addSink(producer) env.execute() the results with: 15:30:44,292 WARN org.apache.flink.kinesis.shaded.com.amazonaws.services.kinesis.producer.LogInputStreamReader - [2020-12-14 15:30:44.292188] [0x0000cb5f][0x000070000512c000] [warning] [AWS Log: WARN](AWSClient)If the signature check failed.
