Unsigned 4-byte receive problem

[111385]

Hello, everyone.
I'm using Bluetooth to receive 4 bytes of unsigned.
I wonder why the block on the left and the block on the right are different.

Receive normally when using the block on the left. However, this runtime error occurs when you use the block on the right.

I want to get up to 5 to 6 bytes, so I'd appreciate it if you could tell me the solution.

Just for your information, get as many bytes as you can. This block is not available on my system.

The block on the left receives a four byte number. The block on the right receives a list of four separate bytes.
