help drawtag graffiti mod

[MtaBrasilBr]

I recently opened an MTASA server, I had this drawing mod on my old server and I would like to know how I can fix these errors that appear in the console.

I had already asked aki earlier, but I ran out of pc and had no way to answer the topic.

 

Here are the errors:
