We are working on a custom PortableText parser in C#, with the possibility to also define some custom parsers for certain HTML elements.
In the example below, the blocks prop contains the output of our parser, but there is a problem, that makes it unrecognizable for @sanity/block-content-to-react. On line 20, our parser would add a marks: [], empty array, that stops the BlockContent rendering with the error:
Cannot read property '_type' of undefined
Removing/commenting out the line fixes the problem. Under the custom image block, we also have a _type: span item which similarily holds an empty marks: [] block, but causes no problem for BlockContent. Why is that?
