As suggested in another post I updated to latest volumio (I’m using a raspberry PI 1B) in order to use latest version of spotify plugin.
Once at the authorize step (I succesfully logged to spotify with my account), once I click on the authorize button nothing happens.
Looking at /var/log/volumio.log I get this error every time I click on it
error: Failed callmethod call: TypeError: Cannot read property 'substring' of undefined
Any hint on what to look at to further debug this issue?
