[Bug]: Error when displaying the tooltip as of Lizmap 3.8

[guenterw]

What is the bug? (in English)

when activating the display of tooltips in Lizmap (3.8, 3.9, 3.10) the error “An error prevented to load the tooltip data” appears.
See https://cx21-8.webgis.biz/index.php/view/map?repository=buergergis8&project=bauleitplanung_3_8

In version 3.7 it works perfectly with identical data

Just quickly looking on GitHub, the error

An error prevented to load the tooltip data

comes from tooltip.loading.error

lizmap-web-client/assets/src/modules/Tooltip.js

Line 118 in fc239c6

lizMap.addMessage(lizDict['tooltip.loading.error'], 'danger', true);

About this code, the message must have a higher warning :

console.log(Tooltip layer '${layerName}' could not be loaded.);

Any error in your QGIS Server logs ?

[guenterw]

No, there are no entries in the QGIS error log. Neither in the Lizmap error log (backend).
But in the Apache error.log there is close to this entry:
QFont::fromString: Invalid description '(empty)'

The error also occurs in V3.9 and 3.10

@Gustry @guenterw I confirm this behaviour even in mine 3.8.2 LWC version, with no entry to logs details, only in browser console there is:
Tooltip layer 'psc_cetraro_prova_cat' could not be loaded.


[Gustry]

I'm not sure what is happening, but it works with the test data : https://sandbox.lizmap.com/lizmap_3_8/index.php/view/map?repository=tests&project=tooltip

[Gustry]

I think the issue is when you use the first tab in the plugin when you set the tooltips.
No error occurs if you use the HTML template. Someone can confirm ?

@Gustry here I noticed that tooltips error it come only at map startup, if I close it (by close error modal popup as well as selection dropdown popup) the tooltips tool end to working. The error come out again after a page refresh, and no error in html template but, in template mode there are no contents in tooltips modal popup (in other words, it doesn't works)

@Gustry sorry for mistake in html mode it works but I doesn't seen the contents because of white color font

This is because of your theme

[Antoviscomi]

You're right @Gustry in html it works as expected and also it's customizable with few html tags

@josemvm it's not qgis/html tooltip but @Gustry meants the html model builder located in Map Suggestions under Lizmap Plugin, using the second tab HTML Model as in screenshot

thanks @Antoviscomi

[guenterw]

I can also confirm this.
Just using the HTML template from the Lizmap plugin is enough to make it work.

at least a workaround until the error is corrected

Yes, it's a workaround, but I would keep this HTML template. It's way more powerful, as you can write your own HTML and use QGIS expressions.
