use lc to create question save to database error

[SmallTeddy]

Sometimes, when using the LC command to create a question, the question is successfully generated in the folder, but the console prompts the storage database to report an error：

    assert(typeof value === "string", () => new internal_1.TypeAssertionError("a string", value, target));
                                            ^
