TypeError: 'str' object is not a mapping in Streamforms Forms Pages

[pbspm01]

The saved form data on Forms Pages cannot be displayed for Streamforms, because of the following error:

Running Codered 1.0.1

Have you seen this before?

[vsalvino]

Can you provide the steps to reproduce this error? E.g. What buttons were clicked in what order, or what code snippets were implemented, etc.

Hi @vsalvino,
I've done some tests, and I've found that the error comes on a vanilla install as well.
Steps to reproduce:

1. Follow Codered install instructions at https://docs.coderedcorp.com/wagtail-crx/getting_started/install.html

2. Enable Stream Forms as https://docs.coderedcorp.com/wagtail-crx/features/page_types/stream_forms.html

3. makemigrations / migrate

4. Create a Stream Form (in my case it was single step, containing a Text and a Text input)

5. Check Form submissions -> no records, no error

6. Submit something in the form

7. Check Form submissions -> error

I know, this is more extensive than that is needed for a vanilla install. I've reused my original Pipfile.
I'm pretty sure that Stream Forms worked on 0.25. But in that config the other packages were also older. (The ordinary Forms worked then, and work now without issues).

[vsalvino]

Perfect, thanks for the details. I will investigate.

[vsalvino]

I think this issue was fixed in 1.0.3, for a bug that was introduced in 1.0.0. (#558)

If you have an existing site, can you try the fix in the release notes: https://docs.coderedcorp.com/wagtail-crx/releases/v1.0.3.html

Or on a new site, start with a vanilla install >=1.0.3
