Thanks @tijs, the dependency solved the error. However, now I had another one:

```

I read in a [post](https://forum.flowable.org/t/form-engine-not-initialized-error/1143) a similar situation but I don’t know it was finally solved. I checked the flowable-form-db-changelog.xml and in effect, there are 3 files with this name (I’m working with version 6.2.0).
