This is coming after updating the version of snakeyaml from 1.3 to 2.0

    Please provide reproduction: build files (`build.sbt`, `pom.xml` etc.), what code causes the error. [How to create a Minimal, Reproducible Example](https://stackoverflow.com/help/minimal-reproducible-example) – Dmytro Mitin Apr 06 '23 at 10:11
  • What is snakeyaml 1.3? Mvnrepository knows 1.4-1.33, 2.0 https://mvnrepository.com/artifact/org.yaml/snakeyaml Did you mean snakeyaml 1.33 (1.3x)? – Dmytro Mitin Apr 06 '23 at 10:16

Indeed, snakeyaml 2.0 doesn't have empty-arg constructor for the class org.yaml.snakeyaml.constructor.SafeConstructor.

In snakeyaml 1.33 such constructor existed but was deprecated.

In snakeyaml 2.0 try to replace

import org.yaml.snakeyaml.{LoaderOptions, Yaml}
import org.yaml.snakeyaml.constructor.SafeConstructor

val safeConstructor = new SafeConstructor
val yaml = new Yaml(safeConstructor)

with

val loaderOptions = new LoaderOptions
// loaderOptions.setCodePointLimit(...)
// ...
val safeConstructor = new SafeConstructor(loaderOptions)
val yaml = new Yaml(safeConstructor)

For me it was "uap-java" lib that didn't support "snakeyaml 2.0". Upgrading to latest version (from 1.5.2 to 1.5.4 so far) solved the problem.
