Continuous deploy fails due to webpack config number, works when manually deploying

Hi there,

I’ve just stumbled upon a continuous deployment error due to a number in webpack’s configuration file. The log from the error is as follows:

7:07:19 PM: /opt/build/repo/webpack.config.js:61
7:07:19 PM:       maxEntrypointSize: 300_000,

However, if I manually deploy the site, it works.

Any idea about why it happens?

Thanks in advance.

From this error, it looks like your webpack.config.js file seem to have a syntax error. Based on the webpack documentation, your maxEntrypointSize value should be an integer but your value has an underscore. Can you try changing that value and see if that helps.

Hi Dennis,

Yes, removing the underscore definitely fixes it, although the bug is only present with continuous deployment, not when doing a manual deploy or when building the project. I will remove the underscore by now.
