Error: Call to undefined method MongoDB\Model\CollectionInfo::insertOne()

The namespace eri_mongo does not belong to this module. Is this your custom code ? Or are you using some specific third-party package ? I can not find eri_mongo on drupal.org.

Without an answer from you, I can only hazard three hypotheses, in order of decreasing likelihood.

• The code in the eri_mongo has a bug, trying to insert documents in a collection info instead of a collection.
• The site uses that eri_mongo module, was not installed with Composer and the non-Composer install missed installing the MongoDB PHP library (that missing class is from the MongoDB PHP library, not the MongoDB module suite
• That eri_mongo module is missing the declaration of the dependency on the MongoDB PHP library, or even missing a composer.json altogether

Note that all three may actually be present.

Since none of these seem to be related to the MongoDB module suite, I shall be closing this issue unless you provide more information.

actually eri_mongo is the custom module.

OK, so the issue is in that module: the bug is that the code at that line is trying to use insertOne on the wrong object: it is using the CollectionInfo instead of the Collection.

You can look at the way to insert documents in mongodb/modules/mongodb_storage/src/Queue/Queue.php::createItem();.

No answer over 1 week later, assuming fixed. Feel free to reopen if you need more help.

Automatically closed - issue fixed for 2 weeks with no activity.
