DOM element with ID 'content' not found in page, but application tries to insert content in IPad

While I am running the application in web, It is showing the data.

But when I am running in IPad, It is showing error in Inspect element like

"Uncaught (in promise) Error: DOM element with ID 'content' not found in page, but application tries to insert content."

Can anyone help me on this. Please.

Thanks,
