How to debug conversion to dash compatible

When I am trying to make the necessary changes to make a component dash compatible and run npm prepublish, I receive errors. How do I go about debugging the errors. I dont understand the output or what could be wrong.

Could you paste an example? The main types of errors that will be printed are related to ā€œlintingā€, or code styling. The errors should provide a line number with the error and a code to go along with it. This is provided by eslint

Tahnks @chriddyp, Im not sure how to interpret the error output to spot the errors… see image
