MDX render is printing wrapping HTML tag instead of rendering

[blue148]

After installing the plugin and setting up the config, the output of the MDX file into HTML is "printing" the wrapping div tag as a string instead of rendering it as an HTML tag

gatsby-config.js

There's no way I can see to configure the type of HTML wrapper that I can see. Unsure why this would be outputting the tag as string instead of code

[angelo-martinez]

Same Issue, I started getting it when I updated to mdxv2

[christopher-besch]

I also have the same issue, after updating to gatsby-plugin-mdx v4 and mdxv2.

[lucastobrazil]

Same here

[lucastobrazil]

has anyone found any workarounds?

[angelo-martinez]

I had to build my own. Just made a custom component that I add in the markdown<TableOfContents tableOfContents={props.data.mdx.tableOfContents} /> and then I loop over the tableOfContents.items inside that component.

[lucastobrazil]

@signalwerk any thoughts on whether this is a bug or oils be addressed? Seems like basically mdx2 is not supported with the current version due to this...

[longkluong]

Having the same issue sadly.

I couldn't figure out how to fix the tests, but I published @ricale's patch as a new npm package to use in the meantime.
