When I'm trying to run updateMany() in the following way, my server returns an error:
db.collection.updateMany( <query>, <pipeline> );
Error: Error: the update operation document must contain atomic operators.
When I'm using update() instead, it works. Using it like so:
db.collection.update(
<query>,
<pipeline>,
{
multi: true
}
);
I tried in on version 4.2 and 4.4 - no difference. The exact code looks like this:
Doesn't work:
db.getCollection("testsets").updateMany( { properties: { $exists: true } }, [ { $set: { "documentProperties.documentCategory": "$properties.documentCategory", "documentProperties.pageCategories": "$properties.pageCategories"} }, { $unset: ["properties.documentCategory", "properties.pageCategories"] } ] );
Works:
db.getCollection("testsets").update( { properties: { $exists: true } }, [ { $set: { "documentProperties.documentCategory": "$properties.documentCategory", "documentProperties.pageCategories": "$properties.pageCategories"} }, { $unset: ["properties.documentCategory", "properties.pageCategories"] } ], { multi: true, } );
Error:

Thanks!
