I get the following error when I try to display my survey, what am I missing here? I followed the survey-vue branch

  • browser: Chrome
  • browser version: 91.0.4472.77
  • surveyjs platform (angular or react or jquery or knockout or vue): Vue
  • surveyjs version: 1.8.50

Hello,

Our examples look ok for me. Here the plunker standalone example and there is no any errors there. Could you please fork and modify it to reproduce the problem?

Thanks

@tsv2013 I can't live demo. I am using İnertiaJS. Survey Creator very good working. But don't display my survey.

Hello @tsv2013

Were you able to solve the issue. I have the same problem with Inertia and vue3. The library is not loading

@nediazc We do not have version for vue3 yet. It is in now plans @mrtsglk Unless we do not reproduce the issue, we can't fix. We don't know what should we fix.

Thank you, Andrew
