I am trying to get my project graalvm compatible. I was successfully able to generate the native image with the `--report-unsupported-elements-at-runtime` option. I get the following error when I run the generated native image.

```auto

```

What could be causing this issue?

How did you generate an Uberjar? Did you make sure you compile it or did you compile the other jar (if using lein). What flags did you use?

Are you using `--initialize-at-build-time`?

This was solved with help from @borkdude on the clojurians slack channel. Conversation link - [https://clojurians.slack.com/archives/CAJN79WNT/p1599544654015800](https://clojurians.slack.com/archives/CAJN79WNT/p1599544654015800)
