Imported reference has a TypeError: arrayfilter()

@london6339, this is not a bug of bibcite_import_orcid, bit related with the version of bibcite → you're using.
Likely, you're using version 2 with PHP8. Upgrade to version 3 and the problem will go away.

Thanks for clarifying @rfmarcelino.

I have updated PHP and tried to update to 3.0 and 3.0 dev, but seems like another issue has occurred with bibcite.

You need to run a drush updb or visit /update.php after upgrading.

I have ran drush updb already and it said no pending updates, but when I try to rebuild cache I get this error:

PHP Fatal error:  Declaration of Drupal\bibcite_entity\Normalizer\CslReferenceNormalizer::supportsDenormalization($data, string $type, ?string $format = null, array $context = []): bool must be compatible with Drupal\serialization\Normalizer\NormalizerBase::supportsDenormalization($data, $type, $format = null) in /var/www/html/modules/contrib/bibcite/modules/bibcite_entity/src/Normalizer/CslReferenceNormalizer.php on line 28
 [warning] Drush command terminated abnormally.

Never saw that one :)
I saw that you opened an issue in the bibcite project. Hope you manage to sort it out.

Actually, do you think #1 is caused by this during import?

That's a warning that the DOI is not available in the user profile.

To debug, you can create a reference in the UI and try to view it. I the problem persists, then has nothing to do with the import from ORCID.
