Expected Behavior

No error occurs and we fetch the data successfully.

Screenshot

Environment

Note: User could run cd scripts && python collect_info.py all under project directory to get system information
and paste them here directly.

• Qlib version:
• Python version:
• OS (Windows, Linux, MacOS): Windows
• Commit number (optional, please provide it if you are using the dev version):

Additional Notes

The possible problem is that this API is not returning the full list of 5000+ symbols, but only part of it.

If we want the full list, it must be sourced from somewhere else.
