Problems with 3D armor model

Greetings, I ask for help/advice beacause i have a problems with the 3D models within the configuration of the armors, I do not know what happens but send an error, which does not let me export the mod, and I have to erase the armor to make it work. I have looked for tutorials on YouTube, but none have served me.

It would help me a lot if someone would tell me how to fix this error, I can send the files by Discord, or images of the error code.

The version of MCreator I use is 2022.1

PS: Sorry if my English is not the best, I speak Spanish and I am using a translator to write this.

Thanks you for taking the time to read
