Assets Error: Unknown or bad format (years) at position 0 (y)

Question

I am getting a new error, after no apparent updates from me or the client. The error only appears on pages with this one particular field.

"DateInterval::createFromDateString(): Unknown or bad format ( years) at position 0 (y): The timezone could not be found in the database"

(then a whole description of errors after it - the first from /craftcms/cms/src/helpers/DateTimeHelper.php)

The field in question is an asset field (within a Matrix field). The files are uploaded / stored in an S3 bucket.

Everything was working fine for a few months, now any site or admin page with content from this particular field throws that error.

I have looked at the database and could not spot any obvious errors (to my eyes anyway).

I've also cleared caches and updated asset indexes

Any ideas as to what I am looking for / do next?

Answer 1

In case this effects anyone else, here's what I did to get working:

• update craft to latest version (in this case 3.1.24)
• flush cache using Blitz cache plugin (clear is not enough)
• use Cloudfront and not just S3
• update all asset indexes in cms

That seemed to have done the trick.
