Version

Please specify what version of the library you are using: [3.21.0 and 3.22.0]

First watched in 3.21.0, then updated to 3.22.0, same error. Looked in the repos and did find the same source code. So I guess there was no change so far.

Expected / Desired Behavior / Question

Expect the DynamicForm to load with the taxonomy column and its default value and the correct label

Observed Behavior

I am not sure if it is kinda related to #2028

Loading the DynamicForm break when I have a taxonomy column with a default value. The "default value" seems to have no "label" property and breaks:

Results in:

Some more environment details:

• Tenant default language: en-US
• Site default language: en-US
• Site additional languages: de-DE
• TermStore default language: en-US
• TermStore additional languages: de-DE
• My UI Language: de-DE

but even with UI Lang = en-US it breaks:

I tried with terms with default language only and with both languages.

Maybe another bug? I have a term label which looks like "Part 1 #x7c Part 2". The Part 1 of the label was not shown in the "name" property while debugging, even when including # in the term label is valid!

Steps to Reproduce

1. Create a SPFx webpart using the DynamicForm
2. Create a list with a taxonomy column and a default value set
3. Try to open the DynamicForm for that list
