I receive my data is half with raspberry pi

When ı send my hex data over the rockblock website and trying to recieve like data_recieve example in adafruit rockblock example (https://github.com/adafruit/Adafruit_CircuitPython_RockBlock/blob/main/examples/rockblock_recv_data.py , url of example) ı got my data is half or empty .

There is some data ı try to send over the website and what ı return
as you can see data above is full but below is less than half, it should be like above.
I'm sure i did everything fine (message size or smtg.)
Is there any solution ?

Start with examples/rockblock_recv_data.py and reproduce the report using the RockBLOCK website and Raspberry Pi setup described in the issue. Compare the sent hex payload with the received value, checking message size and empty-response handling; done means identifying the cause and confirming that the full payload is received or documenting the reproducible limit.
