Error on deploy

[PMLS3]

I am using Google Cloud run when deploying my site. The plugin works 100 in development but getting the following build error.

TypeError: debug_1.Debug.extend is not a function at Object. (/usr/src/app/.output/server/node_modules/http-proxy-middleware/dist/plugins/default/debug-proxy-errors-plugin.js:5:29) at Module._compile (node:internal/modules/cjs/loader:1105:14) at Object.Module._extensions..js (node:internal/modules/cjs/loader:1159:10) at Module.load (node:internal/modules/cjs/loader:981:32) at Function.Module._load (node:internal/modules/cjs/loader:822:12) at Module.require (node:internal/modules/cjs/loader:1005:19) at require (node:internal/modules/cjs/helpers:102:18) at Object.

In my docker file I expose port 8080, not sure if the could be the reason? ERROR: (gcloud.run.services.update) Cloud Run error: The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable.
