Error with facets "Expected [START_OBJECT] under [filter], but got a [START_ARRAY]..."

Thanks for reporting the bug. Changed the status to "Needs work" since the automated tests (or the fix) needs changes to pass the pipeline. I added this issue to as "must have" for 🌱 Plan for 8.0.0-beta release Active .

I tried to replicate the issue with latest 8.0.x branch, I created a view search page and added two facets (taxonomy term and node-id) but unfortunately I was not able to get any error message. Would you be able to replicate the error with fresh site and latest version of Elasticsearch connector 8.0.x module?

Hi Sokru, thanks for the review I'll give it a try asap and report back

I'm still having the issue with the 8.0.x-dev version :
400 Bad Request: {"error":{"root_cause":[{"type":"parsing_exception","reason":"Expected [START_OBJECT] under [filter], but got a [START_ARRAY] in [product_language_filtered]","line":1,"col":542}],"type":"parsing_exception","reason":"Expected [START_OBJECT] under [filter], but got a [START_ARRAY] in [product_language_filtered]","line":1,"col":542},"status":400}

See xDebug of the variable when the problem occurs : https://ibb.co/891yjXR

Still having the issue, docker image docker.elastic.co/elasticsearch/elasticsearch:8.14.3

Version: 8.14.3, Build: docker/d55f984299e0e88dee72ebd8255f7ff130859ad0/2024-07-07T22:04:49.882652950Z, JVM: 22.0.1

Drupal 10.3.2, module version 8.0.x-dev

2 facets, string (list string field) and entity reference, some combination are working, but most of combinations leads too:

{"error":{"root_cause":[{"type":"parsing_exception","reason":"Expected [START_OBJECT] under [filter], but got a [START_ARRAY] in [field_content_reference_filtered]","line":1,"col":358}],"type":"parsing_exception","reason":"Expected [START_OBJECT] under [filter], but got a [START_ARRAY] in [field_content_reference_filtered]","line":1,"col":358},"status":400}
