MediaWiki Semantic Template: Property "Title" (as page type) with input value

Question

A few months ago I asked a very similar question but the cause of the problem this time is different.

The error message is:

Property "Title" (as page type) with input value "Lo psicologo di base rischia di essere inutile se non ci sono abbastanza fondi stanziati

italianTitle = {{{italianTitle}}}" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.

Here I'm using an {{#if inside a template. The property italianTitle is optional

<includeonly>[{{{url}}} {{#if:{{{italianTitle|}}}|{{{italianTitle}}}|{{{title}}}}}] - {{{tags}}} {{#subobject:
|url = {{{url}}}
|title = {{{title}}}

{{#if:{{{italianTitle|}}}|
|italianTitle = {{{italianTitle}}}
}}

|tags={{{tags}}}|+sep=,}}</includeonly>
<noinclude>
{{man}}

== Esempi:==

{{SemanticLink|url=https://www.instagram.com/p/CY_t7QhIWTD/|title=Lo psicologo di base rischia di essere inutile se non ci sono abbastanza fondi stanziati|tags=psicologia,governo,politica,lavoro}}

{{SemanticLink|url=https://www.instagram.com/p/CY_t7QhIWTD/|title=english title|italianTitle=italian title|tags=psicologia,governo,politica,lavoro}}

This MediaWiki template is used to create a semantic link, which is a link to a webpage with additional information (in a Semantic Mediawiki subobject) such as a title and tags.

The template has the following parts:

• The first part, [{{{url}}} {{#if:{{{italianTitle|}}}|{{{italianTitle}}}|{{{title}}}}}], creates the link to the webpage specified by the "url" parameter. It also displays the title of the webpage, which can be specified by either the "title" or "italianTitle" parameter.

• The #if function checks if the "italianTitle" parameter is passed, if it is, it will be used as the title, otherwise, the title parameter will be used. The second part, {{{tags}}}, displays the tags associated with the webpage, which can be specified by the "tags" parameter.

• The third part, {{#subobject:|url = {{{url}}}|title = {{{title}}}|italianTitle = {{{italianTitle}}}|tags={{{tags}}}|+sep=,}}, creates a subobject which is a container for additional information related to the link. Here it contains the url, title, italianTitle and tags parameters. The +sep=, is used to separate the tags with a comma when they are displayed.

• The triple curly brackets, {{{ }}} , are used to define template parameters. When the template is used on a page, the text inside the curly brackets is replaced by the value passed to the corresponding parameter.

For example, the {{{url}}} will be replaced by the value passed to the "url" parameter when the template is used, {{{title}}} will be replaced by the value passed to the "title" parameter and so on.
