Error Unknown metadata type: folder

Thrawn · January 12, 2024, 9:49am

Server Version#: 1.32.8.7639
Player Version#: Latest IOS and IPAD
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>
When I browse my Plex Library on Ios ipad os, apple tv or nvidia shield
I get the follow error in plex from time to time:

“ Error Unknown metadata type: folder ”
Also I get the warnings
QueryParser: Invalid field ‘contentDirectoryID’ found, ignoring.
QueryParser: Invalid field ‘libraryHubsOnly’ found, ignoring.
QueryParser: Invalid field ‘sectionID’ found, ignoring.

I also from time to time have a problem where plex can not match any items till i restart the plex server.
When trying to match nothing shows up at all . if it’s a tv show I have the content gets put into the right show but with no info about it.

I recently had a problem where I have too many folders watched which was fixed with the help of ChuckPa and I thought this would have fixed the match issue too but I got it again the other day.

Could this be connected with the errors?

Thank you all in advance

These errors ( QueryParser ) are because we’re fixing/improving the API and those changes aren’t finished yet. The apps know how to use it but some parts of PMS aren’t using those fields yet. If you look , it says “ignoring”.

As for not not matching media until PMS restarts; this is a separate problem.
We should look at the file names and folder structure to confirm everything is correct

One problem I see in your logs is how fragmented & slow your DB is.
Queries to lookup metadata or match will fail (timeout) if it’s too fragmented.

Are you familiar with my DBRepair tool which defragments the databases?
Also, are you familiar with / comfortable with using Putty / SSH to log into the Syno at the command line ?

Thrawn · January 12, 2024, 5:04pm

I am not familiar with your DBrepair tool
I am familiar with ssh and if there is a step by step guide I am comfortable with it.

Thrawn · January 12, 2024, 5:06pm

Also is the error unknown metadata type: folder” part of the API fix thing?
that does not say ignore.

Thrawn · January 12, 2024, 5:24pm

Ok I found your tool on github and installed it an ran it.

Which option should I chose in the menu?

ChuckPa · January 12, 2024, 5:28pm

In my tool:

Stop - Auto - Start - Exit

It’s that easy

(it accepts command name or command number)

i normally use it this way (as ‘root’ user after ‘sudo bash’).
This is the only thing I put in the PlexMediaServer shared folder

# /volume1/PlexMediaServer/DBrepair.sh  stop auto start exit

It will do it all in one shot.

Thrawn · January 12, 2024, 5:32pm

Right ran number 2 Auto thing

Guessing it will take quite a bit of time?

ChuckPa · January 12, 2024, 5:33pm

It will show you what it’s doing at every step

The worse the DB is and the bigger it is, the longer it will take.

You’ll see a big improvement after it’s done putting it all back together

Thrawn · January 12, 2024, 5:34pm

Thanks a lot.

So my unknown metadata type:

Is this connected to fixing the database or api fix or something else?

ChuckPa · January 12, 2024, 5:35pm

“Unknown metadata type” is solely related to the API queries (internal to PMS)

They truly are harmless right now .

The apps know how to use those extra fields but PMS hasn’t implemented them for all media types

The DB performance will really help with matching and queries.
I’ve seen cases where the search completes (auto-complete) AS HE TYPED
It can/should be nearly instantaneous

Done yet or is it still working?

Thrawn · January 12, 2024, 5:40pm

Thank you so much for your help and answers!

Crap :S

Should not have run it on my tablet
Lost connection while wating too long.

What happens if I run it again from a pc?

Does it ■■■■ something up because it might be already running?

ChuckPa · January 12, 2024, 5:51pm

???

What happened ?

Tablet ssh session failed ?

Diagnostic data

Start tool – It doesn’t touch the DB’s until given the commands to do so.
show command
It will show you everything it’s done.

Share that with me.

Thrawn · January 12, 2024, 5:53pm

See I was lazy and use my iPad to do it

iPad went in standby and the app I used dropped ssh connection and now I can’t see what it’s doing

ChuckPa · January 12, 2024, 5:55pm

SSH rules mean the connection terminates – and all attached processes terminate too

I plan for that.

That’s why I need to see (confirm) where it was at

Start tool
show command to see logfile
Sit there at the menu (On your PC)

Thrawn · January 12, 2024, 6:07pm

so putty pc

How do I copy the text?

Thrawn · January 12, 2024, 6:09pm

ChuckPa · January 12, 2024, 6:09pm

That’s the end of the logfile?

Thrawn · January 12, 2024, 6:10pm

It is yes

Should I just run it again (on pc)?
