Non-existent ReaxFF type

Hi everyone,
I'm a new LAMMPS user, currently, I try to simulate Ti2C3 with some hydrocarbons and using Reaxff for the force field,
I've applied the potential file from:

using pair_style reax/c; lmp_control and param.qeq are also included, but then the simulation went error as stated above,
was that something to do with the potential file? I mean since I'm not using the files which have been built in LAMMPS-stable_3Mar2020 version.
Your advice is very much appreciated, thank you


More likely there is a mistake in your input file.
