Error 404

[Woolage]

When I try to convert it gives an “Error 404”. I checked the log and here's the message

Espo.DEBUG: API (404) Action POST 'getConvertAttributes' does not exist in controller 'Lead'

but I didn't make any changes to the code.

Any suggestion?

Is it possible that you removed some fields? You're trying to convert Lead to Contact? Or what exactly?
