public String pieChart(Model model) {
model.addAttribute("pass", 50);
model.addAttribute("fail", 50);
return "pieChart";
}

The error in the stack trace shows:
Property or field 'content' cannot be found on null
Which means you are trying to call content on something, but that something is null.
The only line in your Thymeleaf template that seems to match this is:
<div col="7" th:utext="${page.content}"></div>
So it means the page model attribute is null.
The controller puts stuff in the model, so we need to look there why this is null:
val page: Page?= pageRepository.findBySlug("home")
if (model != null) {
model.addAttribute("page",page)
}
My guess is that page is null here because there is nothing for slug home in your database?
My index.html lists some reviews, when pressing on the title of one, my controller should get that review's id and use a template view to show only that review's info; it should work with any id/review. I'm searching the internet for 2 hours now and still can't find that syntax I need to achieve this.
This is my current controller:
#GetMapping("/{id}")
public String showSpecificItem(#PathVariable(name="id") Integer id, Model model){
Optional<Review> rev = rev_repo.findById(id);
model.addAttribute("reviews", rev);
return "index-specific";
}
This is the index part with the title:
<div class="container py-5" th:switch="${reviews}"
th:each="review : ${reviews}">
<div class="row">
<div class="col-lg-8 mx-auto">
<ul class="list-group shadow">
<li class="list-group-item">
<div class="media align-items-lg-center flex-column flex-lg-row p-3"
style="overflow: hidden; white-space: nowrap; text-overflow: ellipsis;">
<div class="media-body order-2 order-lg-1">
<form th:action="#{|/${review.id}|}" method="get">
<button type="submit" th:text="${review.title}"
style="color: #100029; text-decoration: none; font-size: 25px; background:none; border: none; margin: 0; padding: 0; cursor: pointer;"></button>
</form>
This is part of the template:
<div class="profile-card">
<div class="text-center profile-back"
style="background-color: rgba(255, 199, 0, 0); width: 70%; margin-top: 10%; margin-left: 15%; height: 100px;"></div>
<h2 class="border rounded profile-name"
style="background-color: #ffc700; color: #100029; width: 432px;" th:text="${reviews.title}"></h2>
<p class="border rounded profile-bio"
style="background-color: #ffffff; color: #100029; margin-left: 15%; width: 70%;" th:text="${reviews.content}"></p>
<div></div>
</div>
Part of the Review entity(rest is just constr, getters and setter):
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
#NotEmpty(message="All fields must be completed!")
#Column(name = "title")
private String title;
#NotEmpty(message="All fields must be completed!")
#Column(name = "content")
private String content;
#NotNull(message="All fields must be completed!")
#Column(name = "score")
private Integer score;
#NotEmpty(message="All fields must be completed!")
#Column(name = "restaurant")
private String restaurant;
And here's the repository, don't know if it's useful or not:
#Repository
public interface ReviewRepository extends CrudRepository <Review, Integer> {
Optional<Review> findById(Integer id);
}
This are the errors I'm getting:

At least it shows me the good id up there...

You pass Optional object to model, but I need to pass the exact value object.
Try this:
rev.ifPresent(reviewsValue -> model.addAttribute("reviews", reviewsValue))
also, You need to remember about fallback action when rev is empty.
eg if (rev.isEmpty()) return "empty-index"
I am currenty trying to build a Headless CMS.
The frontend uses server side rendering.
In my server.js I want to preprocess SCSS
for all files starting from my entry file App.svelte.
Does Svelte.preprocess work on Component.render()?
Does anyone has an idea?
server.js
..
// this registers .svelte files
require('svelte/register');
const App = require('./App.svelte').default;
{html, css, head} = App.render({
pageData
});
reply.view('index', {
pageData: JSON.stringify(pageData),
STATIC_DIR,
html,
// css should output preprocessed CSS
css: css.code,
head
})
./App.svelte
..
<script>
import Navigation from "./components/Navigation.svelte"
import Page from "./components/Page.svelte"
import Header from "./components/Header.svelte"
import Main from "./components/Main.svelte"
import Footer from "./components/Footer.svelte"
import Spinner from "./components/Spinner.svelte"
export let pageData;
console.log(pageData)
</script>
<Spinner></Spinner>
<h1>Das ist ein <span>Test</span></h1>
<Header>
<Navigation data="{pageData['navigation/main']}"/>
</Header>
<Main>
<Page pageData="{pageData['page']}" />
</Main>
<Footer>
<Navigation data="{pageData['navigation/footer']}"/>
</Footer>
<style lang="scss">
h1{
color: red;
span{color: yellow}
}
</style>

I am iterating over a MongoDB document.
where data is FindIterable.
<tr th:each="document, state : ${data}">
<td th:text="${state.count}"></td>
</tr>
state.last not working on iterable? why?
Instead of state.count if i use state.first it prints true for first element and false for all the rest.
When I use state.last it throws an exception.
Why can't I use state.last in this way?
Here is the Exception I got.
org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "state.count + ' ' + state.last"

Using TIBCO JasperReports Server 6.3.0 and adding resources via the rest_v2 endpoint. The resource descriptor for file seems rather simple, and this is the script I am using to test it:
#!/bin/bash
output=$(curl -sX POST "http://localhost:8080/jasperserver/rest_v2/resources/common/someFile.jrtx?createFolders=true" \
-H "Content-Type:application/repository.query+json" \
-H "Accept:application/json" \
-d "{
\"uri\" :\"/common/someFile.jrtx\",
\"label\":\"someFile.jrtx\",
\"description\":\"Some File\",
\"permissionMask\":\"0\",
\"type\":\"jrtx\",
\"content\":\"$(base64 -w 0 /path/to/someFile.jrtx)\"
}" \
--user jasperadmin:jasperadmin)
echo "${output}" | python -m json.tool
The output I am getting for this is puzzling:
[
{
"errorCode": "mandatory.parameter.error",
"message": "A value for the field QueryValue must be set",
"parameters": [
"QueryValue"
]
},
{
"errorCode": "mandatory.parameter.error",
"message": "A value for the field Language must be set",
"parameters": [
"Language"
]
}
]
The descriptor for FILE doesn't mention either of these fields (Language or QueryValue) and I certainly do not have to enter them when manually creating files. What am I doing wrong?

Wrong content type. Instead of this
-H "Content-Type:application/repository.query+json" \
I should use this:
-H "Content-Type:application/repository.file+json" \
