python - updating plugin from qgis 2 to 3. qRegisterResourceData . argument 2 has unexpected type 'str'

I already followed this tutorial and been through the steps. https://github.com/qgis/QGIS/wiki/Plugin-migration-to-QGIS-3 and https://gisforthought.com/updating-a-plugin-from-qgis-2-to-qgis-3/

I make some changes and started to track down the last errors. But im lost with this one:

TypeError: qRegisterResourceData(int, bytes, bytes, bytes): argument 2 has unexpected type 'str' 

I have the following traceback:
