Help needed. Android aapt2 exception for mergeAlphaDebugResources slice 9 images

After an upgrade of an Android project I have taken over, it no longer builds.

It always fails when trying to handle some 9-slice images.

I have tried with different versions of Gradle and I have tried with aapt (1) but always the same problem.
Some files from the same catalog seems to work.

Error from running task assembleDebug:

Task :app:createAlphaDebugCompatibleScreenManifests UP-TO-DATE
Task :app:processAlphaDebugManifest UP-TO-DATE
Task :app:fabricGenerateResourcesAlphaDebug
Task :app:generateAlphaDebugResValues UP-TO-DATE
Task :app:generateAlphaDebugResources UP-TO-DATE
Task :app:mergeAlphaDebugResources FAILED

FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ‘:app:mergeAlphaDebugResources’.

java.util.concurrent.ExecutionException: Android resource compilation failed

Any input?
