Phaser group and Pixi generateTexture error

[proyb2]

I get Uncaught TypeError: Cannot read property 'hasLoaded' of undefined since the generateTexture() is a originally from Pixi API and group.create is part of Phaser API. How do I get pass the error?

 

    var hd1=new Phaser.BitmapText(gnote,0,0,'Arvx','H',54).generateTexture()

    var hd2=new Phaser.BitmapText(gnote,0,0,'Arvx','h',54).generateTexture()

    

    var sprite1=gnote.add.sprite(0,0,hd1,hd2)

    group.enableBody=true

    group.create(50, 150, sprite1) //Uncaught TypeError: Cannot read property 'hasLoaded' of undefined
