until in FluentWait cannot be applied - java

Question

I've had a helper class for Selenium that worked like a charm previously, and out of the blue, this issue came up.

I've also attached a screenshot of the affected functions.

until (java.util.function.Function) in FluentWait cannot be applied to (org.openqa.selenium.support.ui.ExpectedCondition)   reason: no instance(s) of type variable(s) V exist so that ExpectedCondition conforms to Function

Answer 1

The solution that worked for me was to update the jre used by Intellij. that resolved the issue.

Update: Google Guava 23.0 also fixed the issue for some people.
