My builds (even reran of previously successful builds) are failing before of some npm error during the pre-script stages.

404 Not Found: har-validator@5.1.2

For example, this build https://travis-ci.com/ibcol/ibcol/builds/90942352

Version 5.1.2 does not exist. https://www.npmjs.com/package/har-validator

Please update your dependencies.

@BanzaiMan is right, just run

npm install har-validator@latest --save-dev

It’s strange, I think the developer removed version 5.1.2 as the same set of commits were working fine over the weekend.
Updated to 5.1.3 and everything is working fine now.
