Getting "java.lang.NoSuchMethodError: org.bouncycastle.util.BigIntegers.fromUnsignedByteArray" Error.

I am Getting "java.lang.NoSuchMethodError: org.bouncycastle.util.BigIntegers.fromUnsignedByteArray" Error. Can you please tell which version of bouncycastle is recommended for 5.1.0 webpush-java. I have tried 1.60 to 1.64. Nothing seems to be working for me. Am I missing something? Please suggest.

Stack Trace:

c.k.r.c.handler.APIExceptionHandler.handleException - Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: org.bouncycastle.util.BigIntegers.fromUnsignedByteArray([B)Ljava/math/BigInteger;

Hi @debabratapatra I'm facing the same issue. Have you figured out how to fix it? The problem on my side maybe is a conflict with another lib, jasper, that also uses the bouncyCastle.
