Vaadin 24.8 maven build fails

Flow

Hei, I made a simple Vaadin version update 24.7.8 → 24.8.3 (nothing else was changed) but now getting the following error during the build:

Failed to execute goal com.vaadin:vaadin-maven-plugin:24.8.3:build-frontend (default) on project myiUI: null: MojoFailureException: InvocationTargetException: class com.fasterxml.jackson.databind.node.MissingNode cannot be cast to class com.fasterxml.jackson.databind.node.ObjectNode (com.fasterxml.jackson.databind.node.MissingNode and com.fasterxml.jackson.databind.node.ObjectNode are in unnamed module of loader com.vaadin.flow.plugin.maven.Reflector$ReflectorClassLoader @3fb65fb2)

Also this error appeared:
[ERROR] Failed to read token file content.
java.nio.file.NoSuchFileException: /target/classes/META-INF/VAADIN/config/flow-build-info.json

Checked also the fasterxml dependencies but that seems to be the same version (2.19.1) everywhere.

Any ideas how to handle this are welcome :)

How did you run the build? Missing flow-build-info.json makes me think that the prepare-frontend goal has not been executed.
IIRC this was identified as the cause in another forum post or issue on Flow repository,

Adding the explicit prepare-frontend goal did the trick, thanks Marco :)
