JSON content is not indexed or processed

Hello. I have some problems when searching in the dokuwiki search engine, because apparently the json content is not indexed and is completely invisible to the search engine. All the content of tables, variables, etc... does not appear in the search results. It seems that the renderer does not process all that information during indexing. It also doesn't work if I use an h1 tag with an embedded variable taken from the json. In this case the page title does not use the json information if the useheading option is set to true.

Can it be resolved in some way? Thank you for your fantastic work
