webpack 4 e.search error

[anjapadu]

I recently migrated to web pack 4 and found this error:

[Error] TypeError: value.search is not a function. (In 'value.search(pattern)', 'value.search' is undefined)
	hasHtmlTags (utils.js:31)
	getLocalizedElement (utils.js:26)

This is the only library that presents this error its something bad or could be a web pack bug?

To confirm this is build error and not a runtime error?
