How to solve error in loading bcrypt_lib when building docker-compose?

Question

Node.js

Good evening, I'm trying to run an application and cluster mongodb on docker containers. But on startup, an error occurs in the bcrypt library. Application code , some files used in the docker are not yet committed and are not on the github.

internal/modules/cjs/loader.js:1122
return process.dlopen(module, path.toNamespacedPath(filename));
^
Error: Error loading shared library /app/node_modules/bcrypt/lib/binding/napi-v3/bcrypt_lib.node: Exec format error
