@superhail I'm sorry, I have no way to manually generate data to reproduce it.It only occurs occasionally in our queries.

@kssenii Hi, How can I rerun CI?

@kssenii Ok, Thank you very much.

@kssenii The etag should just be a random string, and I have no way of knowing its value. Can I just check if it is empty here?

 @kssenii Hi, It seems that I can't find what caused the error from this.
