An unset KOMPUTE_ENV_DEBUG_LAYERS leads KP_LOG_DEBUG to pass envLayerNamesVal==nullptr along to fmt, which rejects that due to "string pointer is null".

An unset KOMPUTE_ENV_DEBUG_LAYERS leads KP_LOG_DEBUG to pass envLayerNamesVal==nullptr along to fmt, which rejects that due to "string pointer is null".

I used kompute/0.8.0 and fmt/8.0.1.
The relevant entries of the stack trace are level 19 line 182 in Manager.cpp (KP_LOG_DEBUG) and level 10 line 1926 in format.h (FMT_THROW).

Thank you for reporting this @ItsBasi , I was able to confirm with 7.x fmt library with KOMPUTE_OPT_ENABLE_SPDLOG=0 is set. I have now added #246 as fix.
