TypeError: Cannot read property 'expression' of undefined about jsx-ast-utils HOT 7 CLOSED

Can you elaborate on when this happens, on what code?

from jsx-ast-utils.

I will try to dig deeper later to figure out which component is causing that. For now I added a check on .extract function to verify if the value is not undefined fist and it started working again.

I was able to figure out which part of the code is breaking. Doesn't seen to make a lot of sense.

<Link
          className={s.sortable}
          to={{
            pathname,
            query: {
              ...query,
              sort: `${sortKey}-${dir === 'asc' && isSorting ? 'desc' : 'asc'}`,
            },
          }}
        >
          {children}
</Link>

I fixed it by extracting the object inside to= to a new variable and passing the variable instead. It fixed the problem.

I had the same issue.

Before (errors):

<Link to={{
  pathname: '/sign-up',
  state: { ...get(this.props.location, 'state', {}) },
}} />

After (no errors):

const state = { ...get(this.props.location, 'state', {}) };
...
<Link to={{
  pathname: '/sign-up',
  state,
}} />

A PR would be great.

Can confirm that I had the same issue, also when attempting to spread an object in a ReactRouter Link component.

Before(errors):

<Link to={{ pathname: manageRoute, state: {...data}}>Manage</Link>

After(no errors):

const stateForLink = {...data};
...
<Link to={{ pathname: manageRoute, state: stateForLink}>Manage</Link>

Unfortunately I cannot share the full PR.
