Log Entry Question

1

Does anyone know of a good resource to help understand HA log messages?

As an example, I had the below in my logs this morning but I don’t know which script it’s referring to.

Logger: frontend.js.latest.202305033
Source: components/system_log/__init__.py:257 
First occurred: June 2, 2023 at 11:33:22 PM (1 occurrences)
Last logged: June 2, 2023 at 11:33:22 PM

:0:0 Script error.

Also, I would like to be able to understand exactly what this type of log message is trying to tell me:

Logger: homeassistant.helpers.event
Source: core.py:1225 
First occurred: June 2, 2023 at 6:44:04 PM (17 occurrences) 
Last logged: June 2, 2023 at 11:28:58 PM

You are exceeding the maximum possible length for a state. Attributes can be longer.

Thanks Tom. Regarding the first example, do you know where can I find out more about deciphering that type of log message? I haven’t got a clue what it’s referring to, apart from it being a script…or are we not supposed to know?

You can search the open issues in the home assistant github repositories.

You might get more information in the JS console of your browser (development tools)
