Android DataBindingUtil.inflate causes InvocationTargetException

Question

I'm working on an android application that registers consumptions of materials for production in warehouses. I am using Androids UI Navigation architecture component to handle the navigation within the app. In every Fragment I am using the same onCreateView function:

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    binding = DataBindingUtil.inflate(inflater, R.layout.fragment_layout, container, false)

    return inflater.inflate(R.layout.fragment_layout, container, false)
}

where fragment_layout is the resource id of the current Fragments layout.

My problem now is, that in one single Fragment the call to DataBindingUtil.inflate is causing an InvocationTargetException.

I already commented out the complete layout to check if some errors are present in the layout file. After that, I commented out all the logic for the views inside the fragment. This led to the same exception over and over again.

The last test I did was to change the line code inside onCreateView from

binding = DataBindingUtil.inflate(inflater, R.layout.consumption_fragment, container, false)

return binding.root

to:

return inflater.inflate(R.layout.fragment_layout, container, false)

After that, all the problems were gone. But this solution is not suitable for me because I need to use the data bindings.

This is the data section of the layout file in question

<data>
    <import type="Field" />
    <import type="androidx.lifecycle.LiveData" />
    <import type="java.util.List" />
        <variable
            name="parcelNo"
            type="Field&lt;String>" />
        <variable
            name="piece"
            type="Field&lt;String>" />

        <variable
            name="parcels"
            type="LiveData&lt;List&lt;Consumption>>" />

        <variable
            name="parcel"
            type="LiveData&lt;Parcel>" />
    </data>

The stack trace that is shown in the logcat does not provide very much information about where the error occurs.
