`Sprite.command` unreliable

[akaihola]

I have this script, almost straight from the README:

import os

from sprites import SpritesClient

# Create a client
client = SpritesClient(token=os.environ["SPRITES_TOKEN"])

# Get a sprite handle
sprite = client.sprite("my-sprite")

# Use the Go-style API
cmd = sprite.command("ls", "-la")
output = cmd.output()
print(output.decode())

And I've installed dependencies:

$ uv pip install sprites-py
Resolved 8 packages in 8ms
Installed 8 packages in 10ms

 + h11==0.16.0
 + httpcore==1.0.9
 + httpx==0.28.1
 + idna==3.11
 + sprites-py==0.0.1

This always works:

❯ sprite exec -s my-sprite hostname
my-sprite

But this only occasionally works:

$ python sprites_command.py

  File "sprites_command.py", line 13, in <module>
    output = cmd.output()
  File "sprites/exec.py", line 128, in output
