How to display many objects in Three.js?

Question

css

Hello, I am working on an interactive site that is divided into blocks (4 blocks) of the fullpage.js plugin. On each block there are three popubs and 3D models in them.
On one of the blocks there is a background written in three.js, I try to embed popub with a model there, but the console tells me: WebGL: INVALID_OPERATION: uniform3fv: location is not from current program.
Help, please solve the problem.
