you really saved my life, a hug from Brazil
Thank you so much
Thank you so much Nikhil !! I had to create custom file upload component since lightning-datatable component does not work when we want it within visualforce page. So encapsulated this within aura component which in turn was encapsulated inside a visualforce page. This works great !! Only minor difference is uploaded file extension is not displayed(not a big deal). Could you please give some pointers about how to write jest method for this and provide test data for event.target.files[0].
@salesforce Troop does it supports upto 2 GB file upload? I tried uploading larger files and was getting heap size issues while breaking data into small chunks to process.
You need to use the chunk technique
@@salesforcetroop yeah I tried chunking approach but getting heap size limit when uploading more than 6MB files.. have you tried uploading 2 GB files with this? also with Standard file upload component I Can do that but I don't need the progress bar , how to override that?
@@Mtripathi347 I haven't tried it may be in future I will try and build a video around it.

After following your steps I get an APEX CRUD violation. Is there a way to fix this?
CRUD Violation is coming because of PMD rules setup. You can use these conditions before DML to verify CRUD permission.
