Hello,
You are using very old version of SurveyJS Library:

HTML
https://surveyjs.azureedge.net/0.12.19

It is not even the first official release that we introduced four years ago.
Could you please upgrade to the latest version? The current version is 1.9.4.
In fact, it is another library. We have made so many changes since that.
Your Survey JSONs will continue to work.

Thank you,
Andrew

Hello,

thank you so much for responding me , my problem is displayed only on prod mode , on dev mode it works successfully but when i build my angular app the survey form is not displaying and it displays this error on console (see screenshot) (it can probably due to the default value in matrix multiple choice when i delete default value it works ).

Thanks

Hello,
Another user has reported the same issue.
I have changed this function. Here is the related issue on GitHub and my commit.
The change will be available in v1.9.5.
Could you please past your JSON and probably related code. I could not reproduce the issue and all our unit and functional tests work successfully. It means there is a scenario that is covered by our tests. My colleagues will not approve my PR without unit or function test unless I do not push them.
It is better to reproduce the issue. Otherwise, somebody can change the code and the issue will be again in our library.

Thank you,

Hello,
We use the survey library in an Angular 11 application, and we try to show the attached survey (survey.json).
In dev mode (ng serve) every thing works fine, but when we build prod the app (ng build --configuration=production) the survey screen crashes and we get this js error:

Hope this helps.

Hm,
There is no any matrix question in your JSON.
Do you have a code that creates the matrix or you use another JSON?

Thank you,

Hello,

the component is matrixdropdown:

JavaScript
{
       "type": "matrixdropdown",
       "name": "matrixe1",
       "useDisplayValuesInTitle": false,
       "visibleIf": "{CotisationEmp} = 'Base' and {Regime} = 'Regime general'",
       "width": "600 px",
       "minWidth": "600 px",
       "maxWidth": "600 px",
       "title": "TARIF DES REGIMES COLLECTIFS FACULTATIFS (exprimés en pourcentage du PMSS)",
       "hideNumber": true,
       "defaultValue": {
