Running into this exact issue with Stack -- @vladimirlogachev have you managed to resolve this, by any chance?

[vladimirlogachev]

Nope. :(

[bugthunk]

Ran into this as well. Most vexing. Anything I can do to help? FWIW I'm working on debugging it as well. Edit: not using stack, just plain cabal install.

[bugthunk]

FWIW (again), cabal install -v3 servant-swagger-ui-0.3.5.4.5.0 on a fresh system gives the output found in -> debug_symbol_issue.txt

GHC version is 8.10.7.
