GPIO_PIN mask error on start

Host Environment: Debian, esp-idf SDK 3.3 Target Device: LoPy4

My initialization settings are as follows:

const lmic_pinmap lmic_pins = {
    .spi = { /* MISO */ 19, /* MOSI */ 27, /* SCK */ 5 },
    .rxtx = LMIC_UNUSED_PIN,
#ifdef PGESP_LOPY1
    .nss = 17,
    .rst = 18,
#else
    .nss = 18,
    .rst = LMIC_UNUSED_PIN,
#endif
    .dio = {23, 23, 23} //workaround to use 1 pin for all 3 radio dio pins
};

Based on the discussion here https://forum.pycom.io/topic/3403/wiring-of-dio-pins-of-lora-sx127x-chip-to-esp32/5

My error capture looks as follows:

     lmic: Starting IO initialization

What do you think is going wrong?
Thanks for the port by the way!

EDIT: I am 90% sure the PR #4 resolves this, though I am not able to fully test it
