# 0004: Unknown parameter type

The disassembler can't recognize the type of an opcode parameter. It may happen if the file was compiled with errors or protected, or the number of parameters for this opcode in the script does not match the current [configuration](/edit-modes/opcodes-list-scm.ini.md).

**Possible solutions:** enable the [`IGNORE_UNKNOWN`](/editor/debug-options.md#ignore_unknown) debug option.
