I'm having this error:

{Error code '400': 'Unable to complete operation.'
Error executing tool.: Layer "3657710fff894af28b244f9a13ef1982": Missing 'url' in symbol.
Failed to execute (Export Web Map).
Failed to execute (Export Web Map Task).}

And I don't know why. It's on a point layer but if I uncheck it in the TOC the printting tool works.
I have tried changing the symbology.

Thanks in advance
