I'm creating a StructBlock for StreamField. The goal is to create a block that will upload an image as well as a lot of metadata. The metadata is a mixture of CharBlocks, ImageChooserBlocks and RichTextBlocks.
When I want to make the changes in database using makemigrations I receive the error "ValueError: too many values to unpack (expected 2)"
Preceeding that I get:
File "C:...\models.py", line 66, in CatalogueIndexPage'image', TurnerImageBlock(), File "C:...\wagtail\lib\site-packages\wagtail\wagtailcore\fields.py", line 51, in __init__ self.stream_block = StreamBlock(block_types, required=not self.blank) File "C:...\wagtail\lib\site-packages\wagtail\wagtailcore\blocks\stream_block.py", line 47, in __init__ for name, block in local_blocks:I was thinking that it may be due to too many fields. But that shouldn't be a problem. I have also looked at formatting but can't see any. I've included the models.py code below.

But I'm not experienced enough to see where the problem is in my code.
