fail run npm ci & npm run build

Answer 1

Your issue is already in the logs. Your build treats warnings as errors and your eslint warns of the list of unused variables.

Delete the variables in the mentioned files or make them used and you should be fine.

Edit: looking at your index.js you seem to do imports but never use the imports. So you should remove unused imports.

Answer 2

As Laluka said, As it states in logs: Treating warnings as errors because process.env.CI = true. You could change environmental variable 'CI' to false, or you could fix whatever the warnings are.
