We see intermittent crashes with the following report

I have not seen this crash in 14.0.2. This crash happens intermittently. No exact steps to reproduce.

Hi @Abhishek284,

Thanks for lettings us know. It looks like there may be a messed up string format in there, so we should be able to fix this soon.

Fixed in 14.1.3. You can also prevent this crash if you set your log level to above debug (like info, warning, error).
