Tileset With Single Spritesheet file

I have a tiledmap made in Tiled which uses a png spritesheet, without using .plist or any kind data file for the spritesheet. I have the tmx and tsx files. When I import it into a tileMap object, it gives me an error saying;

[Window] Cannot read property 'getAttribute' of undefined

TypeError: Cannot read property 'getAttribute' of undefined

How can I fix this? What is the way to achieve this? Spritesheet has 48*48 pixel tiles and Tiled uses those tiles.
