Hi @Bac0nj, for some reason, I can't reproduce this bug. Can you retry it with the latest mythril develop version? |

I pulled the latest develop version, and the same issue occurs (myth) (base) justin@HAL ~/codes/mythril develop ± git pull

An assertion violation was triggered.
It is possible to trigger an assertion violation. Note that Solidity assert() statements should only be used to check invariants. Review the transaction trace generated for this issue and either make sure your program logic is correct, or use require() instead of assert() if your goal is to constrain user inputs or enforce preconditions. Remember to validate inputs from both callers (for instance, via passed arguments) and callees (for instance, via return values).

KeyError: 'argument'
(myth) (base) justin@HAL ~/codes/mythril develop ± ./myth version
Mythril version v0.24.8I ran it in debug mode and make a breakpoint in the KeyError line. For the first several rounds the instruction was passed in with the correct "argument" key. But for some reason in a round the keyword was missing. Here's the screenshot of the instruct with missing argument. |
I posted my screenshot of the debug mode and more information about where the KeyError happened. |
