[Bug] Upload component won't broken in Dash 1.20.0 #965

Open NicholasChin opened 3 years ago

NicholasChin commented 3 years ago

Hi, I am trying to use the upload component in one of my apps. Recently upgraded to dash 1.20.0 and have found that the component doesn't work anymore. The debug server gives me an error Cannot read property 'call' of undefined. I have also tried running the examples at https://dash.plotly.com/dash-core-components/upload in a clean virtual environment with dash 1.20.0, pandas 1.2.4 and their associated dependencies installed and the examples also fail with the same error. Additionally I am using python 3.9.5 and Chrome 90.0.4430.93.

Thanks for the report @NicholasChin. I haven't been able to reproduce this though - does it depend what kind of file you upload? What OS are you using? Would you be able to expand the stack trace in that error and post it here?
