Error while running Quarkus Production Jar

Question

The application starts successfully when running the command java -jar target/quarkus-app/quarkus-run.jar

While consuming the API from the external source, I got the 500 response, and below is the log got from the terminal.

ERROR [org.opt.cor.imp.sol.DefaultSolverManager] (pool-2-thread-1) Solving failed for problemId (c447ea05-f9f0-427f-a1de-093dc26100b0).: org.kie.memorycompiler.KieMemor

We are getting the same issue in both PC and EC2 instances.

While running the project in the Qurakus:dev, it is completely working fine.

Please help in understanding the issue and fixing it. Thanks in advance.

Please use JDK instead of JRE

Looks like you're running it with a JRE instead of JDK. Try running java --version and add its output to the question. See also Radovan's link - it was the same issue.
