EOF when reading input?

[Yodo9000]

When I run
belt_balancer_net_free_power_of_2 10 8 | blueprint encode
I get the following output:

EOFError: EOF when reading a line

The first line is the expected blueprint, which can be imported into Factorio successfully, but I also get an error message. I also get the same error message with other settings. Maybe I'm using it incorrectly though; it's not so clear to me what kind of data the different commands expect and return.

Python version is 3.9.19

The error is expected, there is no handling of end of input, the program expects an endless stream of input. There's potential to add handling for ending of the stream if needed, but it's not critical to have it in the cases at least I encountered.

Ah, thanks for the quick reply.
