Newb (me) trying to get a SecretsProvider via ParamManager; catching a NPE with "region must not be null"

[rburcham]

It's clear I do not know the best practice for configuring my java powertools lambda, specifically how to tell powertools in which region it will operate.

private SecretsProvider secretsProvider = ParamManager.getSecretsProvider();

is ultimately throwing

Caused by: java.lang.NullPointerException: region must not be null.

        at software.amazon.lambda.powertools.parameters.SecretsProvider.<init>(SecretsProvider.java:83)

How does one prime the ParamManger with what it needs?

This is during sam build, wherein mvn is firing junit tests.

Hi @rburcham, I am currently reviewing some older discussion topics and see that this topic is still regarding v1 of the library and we have released v2 of the library in the meantime. You can find the Parameters documentation here: https://docs.powertools.aws.dev/lambda/java/latest/utilities/parameters/.

Regarding your issue: During unit tests you should try to mock the provider that you are using such that no remote calls are attempted which is causing the error in your case.

Please let me know if your issue still persists and we can re-open this discussion.
