JUCE Assertion failure in juce_AudioProcessor.cpp:441

Building the project succeeds but when I run the plugin with an executable, AudioPluginHost, Logic Pro or as a standalone, I receive JUCE Assertion failure in juce_AudioProcessor.cpp:441 as the output in Xcode. This prevents the plugin from functioning in AudioPluginHost or Logic Pro.

The error that is displayed is:
JUCE Message Thread (1): EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0)

The block of code where the error occurs is:

void AudioProcessor::validateParameter (AudioProcessorParameter* param)
checkForDuplicateParamID (param);
checkForDuplicateTrimmedParamID (param);

#if JucePlugin_Build_AU
jassert (wrapperType == wrapperType_Undefined || param->getVersionHint() != 0);

Has anyone experienced this before or have any ideas for troubleshooting?

Thank you in advance.

Setup: macOS 12.3.1, Xcode 13.4.1, JUCE 7.0.2

Hi @leehu, thank you for the reply! I Incorporated the version hint into my parameters but it was still giving the same error. I’ve created a new plugin now that contains only the initial juce framework. Building the project succeeds, running the project produces the assertion failure. This occurs when I use the VST3 version with the AudioPluginHost as the executable. This has me confused because I have not added any code or parameters to the plugin.

Do you have any idea why this is occurring?

The Xcode output is this:
