Polymer Dart - Google App engine TemplateSyntaxError

I am trying to deploy my app to Google App Engine but I have this error

< template if="{{!has_unique}}"> TemplateSyntaxError: unexpected char u'!' at 8991

enter image description here

I think it has something to do with the Python Framework and Darts Polymer templates possibly conflicting?

Does anyone else know about this and can think of a solution?

Update: It seems to be trying to parse my Dart templates as Jinja???

Update 2: It was the Dart tags. Wrap the whole build HTML in <!--{% raw %}--> <html></html> <!--{% endraw %}--> to ignore any Jinja unsupported syntax

Solution

  • If Jinja is the problem you can use {% raw %} ...... {% endraw %} to escape.
