I have read all the posts related to issues in starting up raspi gateways but cannot see anything similar to my issue.
I have completed a RASPI3 The Things Network gateway setup using this tutorial.
The whole setup has progressed perfectly until the absolute final connection to The Things Network which returns a simple error, but impossible to debug!
TypeError: cannot concatenate ‘str’ and’NoneType’ objects
The only variation to the tutorial I carried out was during configuring the gateway on Resin panel. Previously Resin had ‘Environmental Variables’, which I presume are equivalent to ‘Device Service Variables’.
Any ideas where to start fault find this ??
