'For what reason can an error occur periodically in the client-side?

I have a Rails application that has several components written in Vue. All components are included in the "pack" file.

These two errors occur periodically in the browser (Safari):

SyntaxError: Unexpected token '|'

TypeError: Object(i.a) is not a function. (In 'Object(i.a)()', 'Object(i.a)' is an instance of Object)

The first error points to this line:

<meta name="csrf-token" content="qRbwC3xngly9Y5hRVLA86upHTEkVwIk10PiOtDWCw00RUkIhGK8UvEIhtUXebkzWaqlxsHPSBaheR1moaY-b9w"/>

I don't understand what the second line points to. The error refers to some function "c" in "node.js:15".

Clicking on it jumps to the comment:

In general, I do not understand what it is.

If reload the page, then everything will be fine. Well, that is the problem occurs randomly.

On the Sentry side, I get nothing. Apparently, this does not reach Sentry, the error is not caught and is not transmitted to Sentry.
