Error in Class: Class did not read input parameter(s): n_scf, CC_scf, f_scf, m_scf, thetai_scf

I'm trying to plot a graph using an EDE model available at:
https://github.com/mwt5345/class_ede/blob/class_ede/notebooks-ede/1-Introduction.ipynb

When I copy and paste the code, I get the following error:

CosmoSevereError:

Error in Class: Class did not read input parameter(s): n_scf, CC_scf, f_scf, m_scf, thetai_scf
It seems that Class is not reading the input parameters related to the scalar field, such as n_scf, thetai_scf, and others...

P.S: I'm using google colab.

Any suggestions?

Thank you very much!
