Phaser doesn't load Json Map(Black Screen)

Phaser 3
1

Hello everyone,
I’m new to using the phaser, and I decided to make a map using the Tiled editor program.
In developing the code to show / execute this map, for some reason it does not load me, despite having always a code 200 and none of 404. I have already seen the path to the files, I already looked for information on the web, I modified the code several times but still haven’t managed to make this work

Hi @Rafael_Silva,
You need to replace this.map with map, because in your case this.map is undefined.
And I would recommend using a more recent version of Phaser, since some things have changed and many bugs have been fixed.
Regards and wellcome!!
