Problem - Support Email Address Not Specified

I have an error in erp next.
I click on the report button
and get a message
Support Email Address Not Specified.
I added the file site_config.json to the end
“Error_report_email”: “

but nothing has changed, the message remains the same.
What am I doing wrong?

Use the correct syntax and check:

"error_report_email": ""

Thank You very match!!!
