Hi! We got a lot of such errors on our production. Do you have any ETA?

Hi @Mironiken, thanks for reaching out. I've actually not been able to reproduce it locally. Do you have a reproduction scenario?

[Mironiken]

Nope. I cannot reproduce it locally either. I can create a build with additional logging and run it on the internal environment. I will notify you if there are any results.
Feel free to share any additional thoughts you may have.
