Hi,

The errors you're seeing indicate an authentication problem with nRF Cloud and its most likely that your device's credentials may not be properly registered with nRF Cloud. Can you try onboarding the device using the nRF Cloud Utils as mentioned in the local onboarding section. After doing this, rebuild and run the location sample.

Best Regards,

It seems you are facing a token authentication issue. How did you provision your DK to nRF Cloud? If you used an AT Token or a specific provisioning script, the device might be trying to authenticate using its IMEI while the Cloud expects its UUID.

Try adding these specific lines to your prj.conf file. This forces the device to use its internal UUID as the Client ID, which often resolves the 'Malformed Token' error:

# Use the internal UUID instead of IMEI for identification
CONFIG_NRF_CLOUD_CLIENT_ID_SRC_INTERNAL_UUID=y
CONFIG_NRF_CLOUD_CLIENT_ID_PREFIX=""
