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 “linting”, 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
