I'm facing this exception a lot of time recently when using dynamic mapping without registration.

here's the stack trace:

Thanks for the input!
What version do you use @mr-unicoder ?

maelmahdy commented

Thanks for your quick response @anisimovyuriy , i'm on v1.8.1.0

anisimovyuriy commented

Can you tried to upgrade to 1.9.0 and issue still persist? if yes maybe you can give me some example that I can reproduce it.

Thanks!

maelmahdy commented

This is solved after upgrading to 1.9.0 but now there's another problem, Mapper.Map<T, TN> fails if the object passed to it is NULL, this was not happening before.

Hi @mr-unicoder,

Thanks a lot for your input and contribution - let me do a hot-fix.

Thanks!
