To anyone who has done Google's Foobar challenge before, have you ever encountered an error like this?

```
Verifying solution...
{
"bytes" : "CAAaIgogQ291bGQgbm90IGZpbmQgJ2Fuc3dlcicgZnVuY3Rpb24"
}

```

I've tested my solution in Visual Studio, and it works fine, and it gives accurate output. I only have 36 hours remaining to submit my solution, and this is the final challenge, so I would really like to get credit for completing it. Here's the code I'm trying to verify:

```
from fractions import *
from math import factorial as fac

def cycle_index(n):
    return [(coeff(term), term) for term in foo(n, n)]

def foo(n, lim):
    soln_set = []
    if n > 0:
        for x in range(lim, 0, -1):
            if x == 1:
                soln_set.append([(1, n)])
            else:
                for y in range(int(n / x), 0, -1):
                    recurse = foo(n - x * y, x - 1)
                    if len(recurse) == 0:
                        soln_set.append([(x, y)])
                    for soln in recurse:
                        soln_set.append([(x, y)] + soln)
    return soln_set

def coeff(term):
    val = 1
    for x, y in term:
        val *= fac(y) * x ** y
    return Fraction(1, val)

def cross(cycle_a, cycle_b):
    term = []
    for len_a, freq_a in cycle_a:
        for len_b, freq_b in cycle_b:
            lcm = len_a * len_b / gcd(len_a, len_b)
            term.append((lcm, int(len_a * freq_a * len_b * freq_b / lcm)))
    return term

def answer(w, h, s):
    total = 0
    cycidx_cols = cycle_index(w)
    cycidx_rows = cycle_index(h)
    for col_coeff, col_cycle in cycidx_cols:
        for row_coeff, row_cycle in cycidx_rows:
            coeff = col_coeff * row_coeff
            cycle = cross(col_cycle, row_cycle)
            value = 1
            for _, power in cycle:
                value *= s ** power
            total += coeff * value
    return total

```

I found someone else's solution last week and verified it through Foobar, but I wanted to write my own to get a deeper understanding. I've compared results side-by-side, and they are exact, so I know my code gives accurate results. 

Out of curiosity, I just retried verifying the other person's solution again, and now I am getting the same error with a slightly different output even though it worked just fine when I tried last week:

```
Verifying solution...
{
"bytes" : "CAEQARABEAEQARABEAEQARABEAEQAQ"
}

```

I'm not sure where else to go. I was so excited that I had come up with my own solution to the challenge, but now I'm panicking that it won't matter. Any suggestions?

**UPDATE - June 29, 2018, 6:00pm CST**  

The deadline passed for me last night, and I was unable to submit my code in time. I made sure to use the `recruitme` command before time ran out just in case I got booted out. However, I am still able to view my current status, and it let me request another Level 5 challenge. So, I will be checking periodically to see if the test cases start showing up again, and I will be sure to update this when they do. I would highly recommend that anyone on lower levels wait until I confirm that this issue is fixed before attempting to request another challenge.

**UPDATE - June 30, 2018, 5:00am CST**  

According to the pattern found by @RobertAnsel, I have completed the challenge. I confirmed this pattern by hardcoding the `answer` function to output solutions to the test cases given in the instructions. The resulting errors matched exactly with the predicted output. I also found an interesting thread on Google's Support Forum ([linked here](https://support.google.com/chrome/forum/AAAAP1KN0B0glB446CoqrQ/?hl=en)) where something similar happened to a bunch of Foobar challengers. It seems like their error was fixed by Google after about three days, but unfortunately, it also looks like a lot of people who timed out were not given another chance. Nevertheless, this will probably resolve itself within the next day or two. I will continue trying to verify and submit my solution until I am successful.

**UPDATE - July 4, 2018, 12:00am CST**
This issue seems to have been more or less resolved. Refer to the chosen answer for more details. Thanks a ton to @RobertAnsel for all the help! Some additional info: I was able to verify my current challenge, but upon submission, I was told that my time for the problem had expired. After logging in again, I was able to request a new challenge. I noticed I was also able to use the `recruitme` command again. I am not sure if this means they did not receive the first request or if you are allowed to use that command multiple times. Regardless, I am relieved that I am able to continue forward with Foobar. Best of luck to the rest of you!
