I was trying to reproduce a turbulent flow inner a pipe following the tutorial below:
https://www.youtube.com/watch?v=IJLROB28nXE

I tried many times, executing each individual step, but I always get an error. I can't find where is my error.

This was the error outputs using different versions of OpenFOAM:

None of these errors are the same and hardly any of them occur at the same location. You don't have an (one) error, you have a ton of them.

1. You don't have a valid header in your controlDict
2. You had a floating point error in the solver
3. A wild bracket appeared
4. Your fvSolution is missing a dict for PIMPLE which would not occur if you ran pisoFOAM. Which means either you did not actually see this error or you are not using pisoFOAM.


I recommend you to follow tobi's tutorials or at least take a more methodical approach to your learning. And for your own benefit, stick to one version. I assure you there are no meaningful changes in OpenFOAM between versions that would prevent you from doing a pipe flow problem even if you go all the way back to OpenFOAM 1.x.x

Ignore the other versions error, considering only this error using .org distribution version 10 (the one I am really using)

I don't know where to start to diagnose where is my error. Which parameters are missing in my model, and which ones are parametrized.

The error message does not mention any of the model parameters files.
