Help correct my aim: Creating a Research Tree Mod

[BlackLibrary]

See code below.  Just playing around after creating some weapon mods, and wondered is it possible to create a pure non-item associated research mod.  Well clearly, after testing, I'm missing something.  Looked through others, and no luck.  So posting to John Q (that means you!).
 
Whats wrong with the below.  Looking to create a mod for a new research topic.  Completing it should open a reference in the ufopaedia for reading.  I'll experiment from there.  Please correct my aim!  is the issue because I must have an actual item with and ID for STR_SOLYENT_GREEN?

If you know, please correct my text so I can see a working example.  Thanks!

Code: [Select]

research:
  - name: STR_SOLYENT_GREEN

    lookup: STR_SOLYENT_GREEN_UFOPEDIA
ufopaedia:
  - id: STR_SOLYENT_GREEN
    type_id: 4
    section: STR_WEAPONS_AND_EQUIPMENT
    requires:
      - STR_SOLYENT_GREEN
    text: STR_SOLYENT_GREEN_UFOPEDIA
extraStrings:

    strings:
      STR_SOLYENT_GREEN: "Solyent Green found in laboratory"
      STR_SOLYENT_GREEN_UFOPEDIA: "Yes...you found out what it is.  It also tastes GREAT!!!"
  - type: en-US
    strings:
      STR_SOLYENT_GREEN: "Solyent Green"
      STR_SOLYENT_GREEN_UFOPEDIA: "Yes...you found out what it is.  It also tastes GREAT!!!"

the "lookup" field refers to another research project. it is generally used to refer say, a sectoid commander to the generic sectoid article.
you have not defined a research topic called "STR_SOLYENT_GREEN_UFOPEDIA".

when defining an article in the ufopaedia as "type_id: 4" (item) you require a corresponding item for it to display.

Warboy.,

Thanks for the info.  Made the following corrections.  However it crashes to desktop when attempting to view the article in the ufopaedia after research is completed.

"type_id: 9" requires an associated UFO to display. If you want a "pure text" article use 8. It's explained in the documentation: https://www.ufopaedia.org/index.php?title=Ruleset_Reference_(OpenXcom)#UFOpaedia_Article
