Vue project access, the console occasionally reports an error

found that the vue project occasionally reported this kind of error, and the frequency was not low. At first, I thought I had defined a variable o, but I looked for it carefully for a long time, but I couldn"t find it. What"s wrong with this and how to avoid it?

o is the compressed variable name in the production environment
you need to test it in the development environment to see which variable has a problem
