GraphQL returning random empty content[] in contentPreview and Production environments #support

Describe the issue:

Every once in a while pages are empty in our site both in content preview and production environment. Build process has no logs of error messages, we simply get an empty page where thereā€™ s nothing in the body because GraphQL returned content:[]

The latest scenario we experienced for this was for a specific page that has two locales: de-AT and de-DE. The de-DE locale showed perfectly, while the ā€œde-ATā€ locale was blank. When inspecting the page-data.json stored in our s3 bucket, we saw that the GraphQL query returned content:[]

Forcing a chance on the model (slug change) and building for prod, then undoing the change, and leaving original slug, finally rendered the content. But this doesnā€™t help us understand why there was an content:[] to begin with?

(Optional) Do you have any sample code you can provide?

None, since it happens randomly for different pages, and randomly in either prod or content-preview.

Could you help us with this? Itā€™s very frustrating since we canā€™t seem to pinpoint where the error is happening.

Hey @technology ,

It looks like content in this case is a Modular Content Field, correct? What does your query for that field look like? Are there any filters being applied?

Another thought: Could it have been something to do with the de-AT locale not having been published yet (maybe just saved), and if that was your default locale, the record might come back blank unless you specifically request the de-DE locale? Localization: Fetching Localized Content

(To be safe, you can fetch all of locales together too: Localization: Fetching all locales)

Just throwing some possibilities out there. If you could please provide the query youā€™re using, and what your fetcher looks like, we can keep investigating?

Thanks and sorry about that!
