Hello,
I used dcc.upload() to handle the file upload. The file can be uploaded and read locally on the localhost.
But after the deployment, I received POST 500 internal server error. And the message received is:
{message: “Callback error updating output-data-upload.children”, html: “<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final/…ded or there is an error in the application.”}
The console gives the following error message:

The code related to this error message has been attached below as a screenshot, where output-data-upload is the id of a html.Div() component.
And the upload-data is the id of the dcc.Upload() component.
In the parse_contents() , I’m trying to filter for xls or xlsx files only. in the update_output() , I’m trying to display the name of the uploaded file.
I’ve looked up the 500 error code and have tried to change some permission settings but nothing really worked out.
I really appreciate the help!
