Redis [QUESTION]When using a custom module, an error occurs

int HelloworldRand_RedisCommand(RedisModuleCtx *ctx, RedisModuleString **argv, int argc) { RedisModule_AutoMemory(ctx); if(argc>=2) { size_t len=1024; const char* help=RedisModule_StringPtrLen(argv[1],&len); RedisModule_ReplyWithString(ctx, help); return REDISMODULE_OK; } if(argc==1) { RedisModule_ReplyWithLongLong(ctx, argc); return REDISMODULE_ERR; } } Here is my custom module command，When I use my own command in redis-cli like enter helloworld.rand 123456, the redis-server has a memory error and shuts down directly,Can someone see what is wrong with my custom command
