file size limit

I am working on a shinyapp that involves uploading a file. When I run it locally, everything
works as expected. But, when hosted on I get the following error file upload job was stopped prematurely. The only reference to it I found was in the code for the file upload R6 class but I don't fully understand it. Can anyone help resolve this, please?

EDIT: This seems to happen when I upload a large file. I have set the shiny upload limit to 250MB and tried uploading a file that is ~215MB. Is there a Global file size limit on that I should be aware of?
