Running a deployment on a remote Jenkins node fails as the credentials can not be obtained.

The problem is probably caused by:
private static AmazonWebServicesCredentials lookupNamedCredential(String credentialsId) throws CredentialNotFoundException { final Jenkins jenkins = Jenkins.getInstanceOrNull();
The docs also explain that this method can not be used if it is not running on the Jenkins master node:
/**
* Gets the {@link Jenkins} singleton.
* {@link #get} is what you normally want.
* <p>In certain rare cases you may have code that is intended to run before Jenkins starts or while Jenkins is being shut down.
* For those rare cases use this method.
* <p>In other cases you may have code that might end up running on a remote JVM and not on the Jenkins controller or built-in node.
* For those cases you really should rewrite your code so that when the {@link Callable} is sent over the remoting channel
* it can do whatever it needs without ever referring to {@link Jenkins};
* for example, gather any information you need on the controller side before constructing the callable.
* If you must do a runtime check whether you are in the controller or agent, use {@link JenkinsJVM} rather than this method,
* as merely loading the {@link Jenkins} class file into an agent JVM can cause linkage errors under some conditions.
* @return The instance. Null if the {@link Jenkins} service has not been started, or was already shut down,
* or we are running on an unrelated JVM, typically an agent.
* @since 1.653

Steps to reproduce the issue:
- create a Jenkins node that is accessed via SSH
- create AWS credentials in credential management
- create job with awseb-deployment-plugin step that uses the AWS credentials
- run job on remote node
The same issue was reproduced with the same steps.
Plugin version - 0.3.21
Jenkins 2.362.0
As a workaround, downgrading to the previous plugin version 0.3.19 helps
( be careful with incompatibilities between versions and save your plugin params before )
