Uncaught TypeError: Object(...) is not a function -- version mismatch

What is the current behavior?

I am attempting to upgrade creator to 1.9.64, while using the latest core version: 1.9.71. I get this error with a blank page when trying to use the creator. Uncaught TypeError: Object(...) is not a function.

This is an issue because we want to use the latest version of the creator we paid for, while still being able to get the latest core version. The creator should pint the version without ^.

What is the expected behavior?

Expected it to work fine, even with different versions.

How would you reproduce the current behavior (if this is a bug)?

Listed the dependencies of your package.json as follows:

  "survey-core": "^1.9.71",
  "survey-creator-core": "^1.9.64",
  "survey-creator-react": "^1.9.64",
  "survey-react": "^1.9.71",

Provide the test code and the tested page URL (if applicable)

@nehemiah-tzur Please make sure you have the same version for all libraries and it is better to remove "survey-react" and use "survey-react-ui".
In fact "survey-creator-react" will install: "survey-core", "survey-creator-core" and "survey-react-ui".
"survey-react" is a bundle of "survey-core" and "survey-react-ui". You have two instance of SurveyJS Library in your app.

Thank you,

But i would like to use the latest survey core. Whereas my survey-creator license only allows me a previous version.

@nehemiah-tzur You can't use different versions of survey-core and "survey-creator-xxx". We are generating an error in console in this case.
Please ask your management to renewal the subscription, you will get 60% discount on renewal comparing with initial price, and continue to use latest versions.

Thank you,

@andrewtelnov Many package managers (e.g. Yarn) can handle multiple different versions of dependencies, and each package gets the one it wants. If you could change the creator packages to depend on pinned versions of the other packages (e.g. 1.9.64 instead of ^1.9.64) that would solve the problem. And for those who don't have supporting package managers, it would prevent installing an unsupported combination, so a win in either case.

It's also semantically more accurate, because ^1.9.64 implies that any later minor version of survey-core and survey-react-ui will work with an earlier version of survey-creator-react, which isn't true in practice.

Is this something you could consider?

@llimos I don't think we need to support different versions of our SurveyJS Library for SurveyJS Creator. I do not see any benefits from it except the headache. We are often need to support a new functionality in Creator that has been introduced in SurveyJS Library. The opposite is true as well. Sometimes we need to add new functionality in SurveyJS Library to impement someting in Creator.

We are worried that all JSONs and code that works in early versions of SurveyJS Library and SurveyJS Creator continue to work in new version. We are doing our best to avoid breaking changes.

Thank you,
