Debuging bud errors

Hi, I need help to understand this kind of error in the console:

'./node_modules/@roots/bud-server/lib/cjs/client/indicator/indicator.pulse.js'

As the job progresses the error changes. A new one appears and the old one disappears, but there is always an error there:

Regardless of the error that appears, the page seems to work fine:

What does it mean? Thanks!
