Compilation error while upgrading from 2.7 to 2.8

[leon3s]

Im experiencing a compilation error while i tried to upgrade from ntex 2.7 to ntex 2.8:

error: queries overflow the depth limit!

It seems to come from the middlewares, if i comment the cors middleware it's compile, and if i uncomment it it's still compile, it just fail the first time. But this workarround cannot be done in the CI, any idea how i can fix this ?

as simplest solution you can add #![recursion_limit = "256"] to lib.rs or main.rs

I will check types

[fafhrd91]

could you poss full output of the compiler

This is only what i have:

error: could not compile nanocld (bin "nanocld") due to 1 previous error

Maybe it's a rust bug ? because as i said im able to make the same code compile by just commenting and uncommenting one line..

[fafhrd91]

could you try different version of rust?

[leon3s]

i tried with 1.78, 1.79, 1.80, 1.81 and 1.82 and i still have the issue. I cannot go lower then 1.78 as the latest version of diesel request 1.78 or more.

[fafhrd91]

what project are you trying to build?

[leon3s]

My project nanocl

[leon3s]

I can probably create a repository to reproduce the problem

[leon3s]

I was able to reproduce it with on this small repository:

https://github.com/leon3s/ntex-compile-error

[leon3s]

And this is the code of my middlewares: https://github.com/next-hat/nanocl/tree/nightly/crates/nanocl_utils/src/ntex/middlewares

But i dont do anything crazy with the types
