      QByteArray Constructor - it does work as expected.

      from PySide6.QtCore import QByteArray
rawbytes = b'aaaaaaaaaaaa'
print("rawbytes type =",type(rawbytes))
qbytearray = QByteArray(rawbytes)
print(qbytearray.data())

      QByteArray static method fromRawBytes:

      from PySide6.QtCore import QByteArray
rawbytes = b'aaaaaaaaaaaa'
print("rawbytes type =",type(rawbytes))
qbytearray = QByteArray.fromRawData(rawbytes, len(rawbytes))

      Output:

      rawbytes type = <class 'bytes'>

      Traceback:

      ---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
Cell In[18], line 4
      2 rawbytes = b'aaaaaaaaaaaa'
      3 print("rawbytes type =",type(rawbytes))
----> 4 qbytearray = QByteArray.fromRawData(rawbytes, len(rawbytes))

ValueError: 'PySide6.QtCore.QByteArray.fromRawData' called with wrong argument values:
  PySide6.QtCore.QByteArray.fromRawData(b'aaaaaaaaaaaa', 12)
Found signature:
  PySide6.QtCore.QByteArray.fromRawData(Union[bytes, bytearray, memoryview], int)

      Converting bytes to bytearray doesn't help:

      from PySide6.QtCore import QByteArray
rawbytes = b'aaaaaaaaaaaa'
barray = bytearray(rawbytes)
print("barray type =",type(barray))
qbytearray = QByteArray.fromRawData(barray, len(barray))

      ValueError                                Traceback (most recent call last)
Cell In[20], line 5
      3 barray = bytearray(rawbytes)
      4 print("barray type =",type(barray))
----> 5 qbytearray = QByteArray.fromRawData(barray, len(barray))

ValueError: 'PySide6.QtCore.QByteArray.fromRawData' called with wrong argument values:
  PySide6.QtCore.QByteArray.fromRawData(bytearray(b'aaaaaaaaaaaa'), 12)
Found signature:
  PySide6.QtCore.QByteArray.fromRawData(Union[bytes, bytearray, memoryview], int)
