15.3.0-rc2: FileUploadPropertyValueEditor throws "Invalid content key."

[PeterKvayt]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

15.3.0-rc2

Bug summary

I have content type with block list. Block list item has property with data editor "File upload". While creating new content and filling File upload field in item of block list property I have faced with error: "Invalid content key.".

After investigation I found the issue: block list item does not set 2 props that are required for File upload property editor: ContentKey and PropertyTypeKey. Look at the screenshot (Umbraco.Cms.Core.PropertyEditors.BlockValuePropertyValueEditorBase):

These properties are configured if property is part of content, not is block list item (Umbraco.Cms.Core.Services.ContentEditingServiceBase):

And here are the checks in (FileUploadPropertyValueEditor):

Specifics

No response

Steps to reproduce

1. Create content type with block list property (block list should has item with file upload property)
2. Create new node
3. Fill file upload property
4. Try to save

Expected result / actual result

Expected: content saved, no errors
Actual: an error "Invalid content key." occurred.

Hi there @PeterKvayt!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

Oops, I haven't noticed that Umbraco.FileUpload is not supported for blocks (related discussion).

I have implemented my own custom FileUpload and in the discussion, I shared my experience of how to implement file upload for blocks.

As you've found that this is a known unsupported scenario, I'll close this issue and we'll just keep the discussion you've created about implementing this feature.
