ParseError: syntax error, unexpected '|', expecting ';' or '{'

Hello,

I faced the same issue, removing this part worked for me.

: int|array

I hope it will be updated soon for the next release

Pushed fix to repo. Just needs review.

@geoanders ,I have tested this issue in my local drupal setup.Now showing issue resolved.
No error showing while exporting the content.

Here are the steps I took to reproduce the issue
1.I have Installed module via composer.
2.Then follow this path '/admin/content/content-export'
3.Exported content by provided "Export options"
4.Tested the the csv file & it's content.
We can move it to RTBC +.
Thank you.
