Error while reading the message Body and Labels
Hi Everyone,
I am trying to get the TKB articles from a category, everthing is working fine but I am getting a strange error, when I try to get the Body and the Labels, I get an error: When and why do we get this error?
For "${...}" content: Expected a string or something automatically convertible to string (number, date or boolean), but this evaluated to a sequence+hash (wrapper: f.e.dom.NodeListModel):
==> tkb_details.messages.topic.body [in template "authoritative_content_category_ot" at line 7, column 172]
The failing instruction (FTL stack trace):
----------
==> ${tkb_details.messages.topic.body} [in template "authoritative_content_category_ot" at line 7, column 170]
----------
My Code to read the Body and Labels: The highlighted ones give error
<#assign get_tkb = rest("categories/id/${coreNode.id}?restapi.response_style=view").category.boards>
<#list get_tkb.board as tkb_board_id>
<#if tkb_board_id.interaction_style == "tkb" >
<#assign tkb_articles = rest("boards/id/${tkb_board_id.id}/threads?restapi.response_style=view").threads>
<#list tkb_articles.thread as tkb_details>
${tkb_details.messages.topic.id} - ${tkb_details.messages.topic.subject}, ${tkb_details.messages.topic.last_edit_author.login} - ${tkb_details.messages.topic.body} - ${tkb_details.messages.topic.labels.label.text} <br>
</#list>
</#if>
</#list>

Used this instead:
<#assign tkb_body = rest("messages/id/${tkb_details.messages.topic.id}/body").value>
<#assign tkb_labels = rest("messages/id/${tkb_details.messages.topic.id}/labels").labels>
