Final checklist

• [x ] I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
• [ x] I have included logs, exceptions and / or steps to reproduce the issue.
• [dont know what these are] I have not used any OwO's or UwU's in this issue.

Try oak_log

Also, 1.14.4 has convinient thing called autocompletion. Baritone has it too, it just requires you to press ESC if it's stuck.

oak_log doesnt work aswell, i tried that on 1.12.2 and 1.14.4

try #mine 64 minecraft:oak_log

#mine log does work in 1.12.2

Yes, it doesn't work like that. You need to specify block id at least without the mod that is including it

The expected syntax for 1.12.2 is block:meta, so log:0 would be valid.

The expected syntax for 1.13.2+ is block, because damage/meta values have been removed, so oak_log would be valid.
