Unable to load credentials

[zola33dsf]

Hello,
I'm using aws-kcl v2.2.2 with node js v19.6.0
When i run the node_modules/aws-kcl/bin/kcl-boostrap file i have this issue :

Starting MultiLangDaemon ... java.lang.RuntimeException: java.lang.reflect.InvocationTargetException at software.amazon.kinesis.multilang.config.KinesisClientLibConfigurator.lambda$getConfiguration$0(KinesisClientLibConfigurator.java:67) at java.base/java.lang.Iterable.forEach(Iterable.java:75) at java.base/java.util.Collections$SynchronizedCollection.forEach(Collections.java:2067) at software.amazon.kinesis.multilang.config.KinesisClientLibConfigurator.getConfiguration(KinesisClientLibConfigurator.java:63) at software.amazon.kinesis.multilang.MultiLangDaemonConfig.<init>(MultiLangDaemonConfig.java:108) at software.amazon.kinesis.multilang.MultiLangDaemonConfig.<init>(MultiLangDaemonConfig.java:81) at software.amazon.kinesis.multilang.MultiLangDaemonConfig.<init>(MultiLangDaemonConfig.java:65) at software.amazon.kinesis.multilang.MultiLangDaemon.buildMultiLangDaemonConfig(MultiLangDaemon.java:171) at software.amazon.kinesis.multilang.MultiLangDaemon.main(MultiLangDaemon.java:220) Caused by: java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.apache.commons.beanutils.PropertyUtilsBean.invokeMethod(PropertyUtilsBean.java:2128) at org.apache.commons.beanutils.PropertyUtilsBean.setSimpleProperty(PropertyUtilsBean.java:2109) at org.apache.commons.beanutils.PropertyUtilsBean.setNestedProperty(PropertyUtilsBean.java:1915) at org.apache.commons.beanutils.PropertyUtilsBean.setProperty(PropertyUtilsBean.java:2022) at org.apache.commons.beanutils.BeanUtilsBean.setProperty(BeanUtilsBean.java:1018) at software.amazon.kinesis.multilang.config.KinesisClientLibConfigurator.lambda$getConfiguration$0(KinesisClientLibConfigurator.java:65) ... 8 more Caused by: java.lang.IllegalArgumentException: No credential providers specified at com.amazonaws.auth.AWSCredentialsProviderChain.<init>(AWSCredentialsProviderChain.java:59) at software.amazon.kinesis.multilang.config.AWSCredentialsProviderPropertyValueDecoder.decodeValue(AWSCredentialsProviderPropertyValueDecoder.java:57) at software.amazon.kinesis.multilang.config.MultiLangDaemonConfiguration.lambda$new$0(MultiLangDaemonConfiguration.java:249) at software.amazon.kinesis.multilang.config.BuilderDynaBean.set(BuilderDynaBean.java:258) at software.amazon.kinesis.multilang.config.MultiLangDaemonConfiguration.setAWSCredentialsProvider(MultiLangDaemonConfiguration.java:176) ... 18 more java.lang.reflect.InvocationTargetException

And the AWSCredentialsProvider value in my properties file is like this :

AWSCredentialsProvider = STSAssumeRoleSessionCredentialsProvider|arn:aws:iam::955*********:role/FakeRoleForGithub**********|session2

Do someone have the same problem ?
Please let me know 👍

Hi,
Same issue for me as well

From what I can tell, the java side of the kcl uses reflection to find and load resources from your .properties file. This config:

AWSCredentialsProvider = STSAssumeRoleSessionCredentialsProvider|arn:aws:iam::955*********:role/FakeRoleForGithub**********|session2

lets the process know that it should find a class with the name STSAssumeRoleSessionCredentialsProvider and construct a new instance with arn:aws:iam::955*********:role/FakeRoleForGithub********** being the first argument, and session2 being the second argument passed into the constructor.

I assume that the process can't locate a class called STSAssumeRoleSessionCredentialsProvider and fails to load any credentials and then throws the No credentials found error.

Here's what I did, but please make sure you don't just use this blindly:

1 - I downloaded the java aws-sdk .jar file and stored it locally.
2- I then copied the jar file into my docker container:

COPY ./docker/aws-java-sdk-1.12.496.jar ./java/aws-java-sdk-1.12.496.jar

3 - I then edited my npm script to tell it where my java files are:

# Notice the `--java ./java`
npx kcl-bootstrap -p ./docker/kinesis.properties --jar-path ./java -e

4 - I modified my AWSCredentialsProvider variable in the properties file:

AWSCredentialsProvider=com.amazonaws.auth.STSAssumeRoleSessionCredentialsProvider|{arn}|{sessionName}

So in your case it would be:

AWSCredentialsProvider=com.amazonaws.auth.STSAssumeRoleSessionCredentialsProvider|arn:aws:iam::955*********:role/FakeRoleForGithub**********|session2

I'm not a java guru and it took me loads of reading up to get to this solution, so if i've done anything wrong, please let me know. Hope this helps you

But even if you use default one from example:
AWSCredentialsProvider = DefaultAWSCredentialsProviderChain
It still gives you the same error.
