V3 MINIE not working with U575 custom board

[WellLeithed]

I have a 14-pin connector and a 6-pin fall back connector. I can connect the 6-pin SWD via st-link V2 on a nucleo board but I cannot connect with a V3 MINIE on the 14-pin. Any ideas? I followed the schematic for a 14-pin connector I found on a NUCLEO board, which had a 100 ohm resistor on GND detect. I have bypassed it but the result is still the same. Apart from that and the TX/RX, the wires are the same for the 6-pin connector that works?

Here's my output:

CDLiveWatchSetup
Info : auto-selecting first available session transport "hla_swd". To override use 'transport select <transport>'.
Info : The selected transport took over low-level target control. The results might differ compared to plain JTAG/SWD
Warn : The selected adapter does not support debugging this device in secure mode
adapter speed: 24 kHz

none separate

Info : Listening on port 50004 for tcl connections
Info : Listening on port 50005 for telnet connections
Info : clock speed 24 kHz
Info : STLINK V3J14M5 (API v3) VID:PID 0483:3754

Error: init mode failed (unable to connect to the target)

I've just noticed that the footprint of the connector has pins 5 and 6 mixed up. Anyone have any ideas for removing the trace connecting pins 6 and 7 under the 14-pin connector (hahaha!)? Thank God for the 6-pin fallback the board has. And thank you for your willingness to help.

Use an adaptor cable / interposer to correct it.
