Verifying old code suddenly fails?

Troubleshooting
1

Was working on Weasley clock but original 25 LED string wouldn’t work properly with code. Took the system offline for a month while waiting on 50 light string to be delivered. I tried to push the old code to my Photon last night but get an error when verifying stating " error: ‘number_for_key’ was not declared in this scope".

As mentioned, this is the exact same code so I’m unsure why I am suddenly getting this error. What would something have changed on the Particle end in the past month which would effect this?

This is the code I am using.

Compiler seems to now struggle with certain function prototypes, particularly those that use structs. So, you can try forward declaring the function (as it should be anyway) at the beginning of the .ino (just after the #include directives).

// This #include statement was automatically added by the Particle IDE.
#include "neopixel/neopixel.h"
#include <stdio.h>
#include <string.h>
#include <math.h>

#define PIXEL_COUNT 50

int number_for_key(String key, struct entry dict[]);
// etc ...

Thanks...that seems to have fixed it for me.
