Good day, I use JS and canvas to prepare an image for Sprite
When testing the application on a device using Android 14, a problem arose with the lack of the drawImage function in CanvasRenderingContext2D
Code for identifying the problem
let CoverCanvas = document.createElement(“canvas”);
let Cover_ctx = CoverCanvas.getContext(“2d”);
console.log(‘Direct Cover_ctx:’, Cover_ctx);
console.log(‘Direct Cover_ctx drawImage exists?’, typeof Cover_ctx.drawImage === “function”);
console.log(‘Cover_ctx constructor:’, Cover_ctx.constructor.name);
console.log(‘Cover_ctx prototype:’, Object.getPrototypeOf(Cover_ctx));
console.log(‘Cover_ctx keys:’, Object.keys(Cover_ctx));
if (typeof Cover_ctx.drawImage !== “function”) {
console.error(“Error: Cover_ctx.drawImage is not a function!”, Cover_ctx);
}
if (!Cover_ctx || !(Cover_ctx instanceof CanvasRenderingContext2D)) {
console.log(‘Error: Cover_ctx is not a CanvasRenderingContext2D!’, Cover_ctx);
} else {console.log(‘Cover_ctx is a CanvasRenderingContext2D!’, Cover_ctx);}

There is no such problem in the browser. Tell me where to look for the cause of the problem. Thanks in advance for your help.
