Vaadin 18 Error: Failed to find the following files: ./comboBoxConnector-es6.js

[jonathan97h]

I tested this component v.0.4.0 in Vaadin 18.0.5.

If you start the application the following error appears:

java.lang.IllegalStateException:

Failed to find the following files:

• ./comboBoxConnector-es6.js

  Locations searched were:

• /Users/.../vaadin/frontend in this project

• META-INF/frontend in included JARs

  Please, double check that those files exist. If you use a custom directory for your resource files instead of default frontend folder then make sure you it's correctly configured (e.g. set 'vaadin.frontend.frontend.folder' property)

The error is still the same with Vaadin 21.0.3.

Same for us in Vaadin 22, it's an impediment for us in the migration from 14 -> 22(23)
