Error after M 2.4.0 upgrade: main.CRITICAL: String to be escaped was not valid UTF-8 or could not be converted

[jesperbrejning]

After upgrade from M 2.3.5 to M 2.4.0 we see the following error in frontend: "An error has happened during application run. See exception log for details."

Any Idea how to solve this issue?

Best regards,
Jesper

I'm seeing a bunch of Amasty modules (Page Speed Optimizer & Advanced Search) in your stack trace, can you try the same with those modules disabled, it might be a problem caused by those modules?

If you don't get that error anymore after disabling them, please take contact with Amasty (or try to update those modules to the latest version)

[mrtuvn]

Maybe custom layout feature in amasty advance search module not work in 2.4 anymore

[AntonEvers]

@jesperbrejning try downgrading amasty/xsearch to 1.14.7. In my case this happens right after I upgrade amasty/xsearch from 1.14.7 to 1.14.8. And not only in Magento 2.4, but also on 2.3.

[AntonEvers]

@jesperbrejning I've sent feedback on how to resolve this to Amasty support.

[AntonEvers]

This issue can be closed as Amasty has announced to fix this in their next release.
