2.7.10 may have a bug about function limit()

[Zys97kobe]

I can find 532 pieces of data

but when i used limit(n:20, offset: 530) i got a panic :index out of range

[Zys97kobe]

2.7.9 has no this bug

[Zys97kobe]

This seems to be related to the association of a certain label of a certain piece of data, but the panic only appeared in 2.7.10

@Zys97kobe - any chance you can provide the stack trace as text instead of a screenshot like you did above? It is difficult to read the image.

@philjb OK I posted the log text here
