Running Project Inspector returns Invalid Parameter

Running Project Inspector on an esp32 project returns Invalid Parameter. This is my first attempt to se Project Inspector. I have searched the web for answers with no luck. I have no idea what parameters its talking about. can anyone enlighten as to what this terse message is telling me? Thanks.

Does it work on official projects like arduino-blink? If not → Issue to Issues · platformio/platform-espressif32 · GitHub
