## Exception state
- Type: Informational
- Contract: Rubixi
- Function name: `_function_0x57d4021b`
- PC address: 1653
### Description
A reachable exception (opcode 0xfe) has been detected. This can be caused by type errors, division by zero, out-of-bounds array access, or assert violations. This is acceptable in most situations. Note however that assert() should only be used to check invariants. Use require() for regular input checking.
