JUCE Assertion failure in juce_LV2_Client.cpp:132

Hi there I encountered this error attempting to build an LV2 plugin on Ubuntu

Linking waylodelayUDany - LV2 Plugin
JUCE v7.0.5

JUCE Assertion failure in juce_LV2_Client.cpp:132

seanw@seanw-Legion-Y530-15ICH:~/Desktop/wayloUD/Builds/LinuxMakefile$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.1 LTS
Release:        20.04
Codename:       focal

This is the REPO

I just managed to build another plugin with the make command on the same machine.
No build errors and the plugin loaded in reaper and made a sound.

This one built something but reaper didnt see it I think.

Any ideas ?

// If this is hit, the parameter ID could not be represented directly in the plugin ttl.
// We'll replace offending characters with '_'.
jassert (urlSanitised == ttlSanitised);

This assertion is telling you that one of your parameter IDs contains characters that aren’t valid in the ttl format, used for the plugin manifest file.

This shouldn’t prevent hosts from loading the plugin, but it’s a good idea to make sure your plugin ids only contain alphanumeric characters (no spaces, punctuation etc), assuming you haven’t published a version of the plugin using the current parameter IDs.

thanks I assume it’s the spaces in these arguments in the declaration of the params in the plugin processor class.

I will try and remove them when I have time and report back.

Doing this sort of thing and removing the spaces from the parameter ids got rid of the asserts showing up. I also found the plugin in reaper not sure if I was looking for it wrong before.
thanks !
