I had the same issue
League\Csv\SyntaxError: The header mapper indexes should only contain positive integer or 0. in League\Csv\Reader->computeHeader() (line 448 of [...]/vendor/league/csv/src/Reader.php).
using PHP 8.1.22, Drupal 10.1.7, migrate_source_csv 8.x-3.5, league/csv 9.12.0
The patch at #7 fixed the issue for me as well. Thanks!
Hi there. I have submitted French translations for the new strings.
Thanks for such a useful module :-)
Hi. Ok, Thanks. That makes sense.
Let me know when the updated string has been published and I will translate it.
Yes, it does make sense to me.
Just a typo in the comment for the Domain prefix / No redirect option: it should be "are accessible" instead of "is accessible"
My suggestion for translation in French below, under the English.
===
Text in English:
Domain prefix
(_) No redirect
Both mydomain.com and www.mydomain.com are accessible. Only use this option if you are certain it is needed.
(_) Remove WWW prefix
Redirect www.mydomain.com to mydomain.com.
(_) Add WWW prefix
Redirect mydomain.com to www.mydomain.com.
HTTP Secure (HTTPS) redirect
(_) No redirect
The site remains accessible via HTTP, as well as via HTTPS (if enabled).
(_) Redirect to HTTPS
The site becomes accessible only via HTTPS. All HTTP requests are redirected to HTTPS.
ATTENTION: if you choose this option, make sure your site is accessible by HTTPS, and that your SSL certificate is valid.
