DOMException: "The expression cannot be converted to return the specified type."

[azu]

• fetch: DOMException: "The operation was aborted. "
• XHR: TypeError: "Network request failed"
• fetch + Strea: DOMException: "The expression cannot be converted to return the specified type."

Workaround :

• Greasemonkey CORS script: https://github.com/azu/irodr/blob/master/resources/userScript/irodr-cors.js

This is unknown reason.
Maybe This is caused by subscription size. (I have 5000+subscription)

My workaround is https://github.com/azu/irodr/blob/master/resources/userScript/irodr-cors.js
