Hi, @PabloFerreira. The error is this:
npm ERR! path /opt/build/repo/package.json
The node runtime is saying that package.json doesn’t exist. This is because it doesn’t exist in the repo (this is a 404 page below):
https://github.com/PabloFerreiraB/Aposentaf-ms/blob/master/package.json
There is a package-lock.json file but it is almost empty:
https://github.com/PabloFerreiraB/Aposentaf-ms/blob/master/package-lock.json
To be able to call a package.json script using npm (for example using npm run build), first that script (build in this example) must be defined in package.json. That has not been done and the error is saying the required file is missing.
Also, the following support guide might be helpful here as well:
Please let us know if there are other questions about this.
