Hello @rabberbock ,

Here is a small update:

We have found the issue and know how to fix it.

However, that's not an easy fix, as we need to look at the logic about how EF Core is currently transforming entity into json (they have their own json writer inside the EF Core code for this).

So that's definitely something we will look to support, but the fix might come more in January.

Best Regards,

Jon

@JonathanMagnan Thanks for the update! Looking forward to that fix, thanks!

[rabberbock]

@JonathanMagnan Just curious if you had any updates on your end on this. Thanks!

Hello @rabberbock ,

We are currently completing our top priority (it should be completed by Friday).

Fixing this jsonb column will become the next top priority as soon as it's completed. I'm not sure how long it will take, but we usually try to push as fast as possible our top priority. So I don't have an ETA yet, but it will become our main focus starting from next week, so I should be able to give you an update very soon.

Best Regards,

Jon

@JonathanMagnan Just wanted to check in to see if you have an idea when this will be completed? Thanks either way!

Hello @rabberbock ,

A new version has been released a few hours ago. I will make the release notes later, but you can already try the latest version.

It's still not 100% perfect (we are still working on more complex scenarios such as Owned Many), but most common scenario should already work.

I will let you know more soon.

Best Regards,

Jon

[rabberbock]

@JonathanMagnan Awesome, thanks for the update! Will let you know if we run into any issues.

[JonathanMagnan]

Awesome @rabberbock ,

You can see the release note here, but there is not much additional information besides what I just said.

Sure, we will be happy to look at it and try to support it if you run into any issues. We are still working on the ToJson Mapping for the more complex scenario.

Best Regards,

Jon

Hello @rabberbock,

Since our last conversation, we haven't heard from you.

Let me know if you need more information.

Best regards, Jon

[rabberbock]

@JonathanMagnan I did a quick test and I am still running into issues, will post with more relevant details when I get a chance. My guess is that we will need the more complex scenario support. Thanks!

[JonathanMagnan]

Hello @rabberbock,

Any updates?

Let me know if you need further assistance.

Best regards,

Jon

@JonathanMagnan Sorry for the delay! Just got around to doing some testing and all errors I got were ef issues not related to this library. So everything seems to working great after this update. Thanks!
