Im trying to upload a 1mb File in salesforce lightning component referring this documentation by Peter(http://peterknolle.com/file-upload-lightning-component/) I am able to upload 500KB files using this code, but when I try to upload a 1mb file, i get this error from the server call which is made to the apex class ERROR "Received exception event aura:systemError from server" Any help would be appreciated. Im using the larger file approach of the above mentioned documentation(CHUNK_SIZE)


I faced the same error. I solved it changing the chunk size from 950000 to 750000
