Error Loading Layer

[ismailsunni]

I tried to load a mbtiles using this plugin on QGIS 3.10.11 on Windows 10. The data is coming from

Data: https://osmlab.github.io/osm-qa-tiles/ (Switzerland) GL Style JSON URL: https://raw.githubusercontent.com/openmaptiles/dark-matter-gl-style/master/style.json

The stack trace that I got:

Is there anything that I missed?

I just tried to install it on QGIS 3.10 and 3.16 on Ubuntu 18.04. Unfortunately, right after enabling the plugin, my QGIS crashes. Any idea about this issue?

I'm afraid without a TileJSON url this is not going to work sorry.

Can you retrieve a logfile maybe? Either from QGIS or from the plugin.

Similar crash with QGIS 3.18 and Ubuntu 20.04. Appreciate the following is inelegant but potentially useful:

Running QGIS from command line, so errors logged to terminal whilst installed plugin:

$ qgis QGIS died on signal 11Could not attach to process. If your uid matches the uid of the target process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Operation not permitted. No thread selected No stack. gdb returned 256 Aborted (core dumped)

and

$ sudo qgis Warning: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'

but otherwise plugin installed.
