Helping me run devolpment environment of existing angular 12 + spring boot and mysql project

I received the source code of a angular 12 + spring boot project with mysql database.
I run them both, but have some issues regarding jwt and other things.
I'm looking for someone to help me resolve the issues I have and to be able to run well on my machine.
You will need to help me remotely (zoom/meet).
On next phase you could assist me with developing more features.
