Hello Wolfgang you last, I reconsidered my original solution and indeed found a silly mistake when I calculated the curl of the potential values. Of course then, the implementation that you suggested was correct and simple enough.
Probably, when I added the additional first derivative term, I solved the equation in r * A (or radius * potential), which was fixing the bug in my evaluation of the B field. Sorry for my email flood, and thanks again for your help, hopefully this topic will be useful for someone else in the future.
