JUCE Assertion failure in juce_AudioProcessor.cpp:1073

[claireaxu]

I am just getting started and I tried to build the basic-plugin template for the first time from juce with standalone plug-in mode in Xcode. The build succeeded but this line showed up in the console preventing build. I am a complete beginner and don’t know what is going on. Can anyone help?

The problem is in juce_AudioProcessor.cpp line 1073, assertion failure and invalid layout

You can use the debugger to step into checkBussesLayoutSupported to further determine the cause of failure.

I too just started and followed the tutorial create a basic audio midi plugin from the JUCE tutorials and got the same error: JUCE Assertion failure in juce_VST3PluginFormat.cpp:232

Did you manage to figure out a way around?

Sorry to disagree, but this is not the same error.
JUCE Assertion failure means that an expected condition in a debug build wasn’t met.
The code is full of those jassert calls, each one points to a different problem.
Often you find an explanation in the code next to the line that triggered the stop:

juce-framework/JUCE/blob/master/modules/juce_audio_processors/format_types/juce_VST3PluginFormat.cpp#L232

This means the method was expected to be called from the message thread.
Check your call stack where it was called from. If it was indirectly called from processBlock() this is a problem.
