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:

https://www.cambridge.org/core/journals/journal-of-materials-research/article/molecular-dynamics-simulations-of-the-interactions-between-tio2-nanoparticles-and-water-with-na-and-cl-methanol-and-formic-acid-using-a-reactive-force-field/21596ADFB7558FC775FC104DD4228101

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.
