'FST_ERR_CTP_INVALID_MEDIA_TYPE'

[vinnycosta1998]

I need to send images to the backend and I still have the same problem 'FST_ERR_CTP_INVALID_MEDIA_TYPE', I have already installed @fastify/muiltipart and configured it in the application, below is how I did it

Since there's no runnable code provided, I guess you can try to place the appRoutes to the bottom.
It depends, but sometimes order of registration is important.

Seriously, I did what you wrote and solved this problem, thanks bro.
