E1101 — Non-deterministic actor code

PropertyValue
Code1101
SlugE1101
Categoryvalidation (Validation)
CIPCIP-3 §2.4

​
What happened

Non-deterministic actor code.

​
Why it happened

The actor code uses a banned import, API, or large integer literal that would break consensus determinism. Common triggers: asyncio.gather, import random, import time, ctypes, integer literals exceeding 1,234 digits.

​
How to fix

Remove the flagged construct. Use cowboy_sdk.pvm_random instead of random, cowboy_sdk.pvm_time instead of time, and sequential awaits instead of asyncio.gather. See the PVM Compatibility Rules documentation for the full list.
