Description

SerializedValue allows to wrap null values. Because of this, SerializedValue.getByteArray() might return null which is not properly handled in different locations (it's probably the best to use the IDEs "Find usages" to identify these locations). The most recent findings (for now) are listed in the comments.

We should add null handling in these cases and add tests for these cases.
