That's not one of the basic tests, copy/paste it to sample tests to see your code fail and debug it.

Your code is wrong, not a kata issue. It fails tests like this one:

testing(longest_consec(["zone", "abigail", "theta", "abigail", "form", "libe", "zas"], 2), "abigailtheta")

The code in PyCharm gives you the correct result, but in the tests it is not correct. What could be the error?
print(longest_consec(['ahhhyaann', 'xxpppojta', 'ttiicccxnnnzz', 'eeeraafnbbddqii', 'jwwwsppc', 'uubddy', 'vvvaaaamww', 'zzzhbee', 'yybbbcjjqqqqq', 'kkyygnnn', 'oonghhh', 'vessh', 'ttllae', 'bbbqqqegggm', 'uxfffxxcuuurrrhh', 'ufrrrvvvnfffx', 'bbhhhnnn', 'lllcccekaa', 'zzqqquuugggpaaa', 'zzeeewwuuuvv', 'kkkuujqq', 'diiigggooo', 'rrruuuiiyyoooaaakkiiwww', 'qqdddhhbbuuu', 'cbvvqqqgggee', 'aaaveee', 'zzfffnnnrnoo', 'tttaaauupssswfff', 'nnnnllled', 'jaaaennnyyp', 'llljuuhhhww', 'wwzzzmmmk', 'swwwjjn', 'ccnnnqqqfffoooko', 'obbkkxxddd', 'qlluujjcccjssseeep', 'aamjj', 'aaarrrmmmbhh', 'brrrdvvc', 'mmmtuu', 'fffssnnneuuq', 'rrtttv', 'ggtbbbttooh', 'nnnwwtttlfff', 'ppttttwaaa', 'fnntccckllttt', 'ggooouppp', 'vvhhhdddso', 'xxxnnooqqfjjj', 'cztf', 'fffuubbbb', 'crrrnn', 'sswfooff', 'jjjgggkktttaxxoozz', 'llttyy', 'ymln', 'kkggyyygvvvvvf', 'hhfffimmmvvvsss', 'xjjjkyfqq', 'jyyssddlla', 'hhhrzzzttt', 'eewwbeeq', 'xxfffccbpvvvu', 'ffvvvggggggvf', 'ffofffdddvvqq', 'ffxpppssstttl', 'yyymmkkkzziii', 'ygga', 'feetttcc', 'rrrjdddzqqqfgg', 'vvvssuuuj', 'ssbbbccqkk', 'sazzzvvrrrexbb', 'kkwwwrycs', 'fiyyyaaa', 'sbbbpp', 'oooeeennnoo', 'uuuuuqqqw', 'ndddqqqkh', 'qqqoorm', 'kenncccllqqtx', 'kcccellljsslll', 'qvvvvmmmee', 'eeennnqqqnmmm', 'eovgkkkhhh', 'mnnnkkaaa', 'hhhlbbeeepppw', 'qqqaabbbpppht', 'iicd', 'kkiikj', 'riiii', 'fffoccclwee', 'xxdxxzzzkkzzz', 'hhhccuweeekkk', 'zzzoobbfffllj', 'jkkkggg', 'dvuu', 'iibffwwll', 'yyvff', 'ahhiiipppqqq', 'zzppcccffcchhmmmm', 'wwwxxxpppnnnbyyy', 'ppnnniyyfffn', 'qqzziiu', 'xxxmmmvnnnoww', 'yyzxxl', 'bbjwwtttdp', 'cccnefooojttt', 'mppps', 'mmaasaa', 'wwweeezkqqqo', 'unnoddttt', 'kkjjjcccaaayyy', 'qqehhn', 'rryyjjjfgggvvv', 'gxi', 'pppbbbssjh', 'xiddddhh', 'eeotttfffcc', 'kkkjhooovvvvv', 'qfcccvvvjjj', 'xxxqcjjjummooo', 'reyyy', 'fooeeesssw', 'ttrrpppeyyy', 'hhhdddmmmgnn', 'hrnyyyyttz', 'ddqqaayyyyy', 'hhvaaawwnnnooo', 'ccsskkkuu', 'aaffqqhssjjjjp', 'leeeraaabbkkk', 'vvvyyshhhssse', 'fzzmmmfff', 'fvooyyygbbdnppp', 'hhsssdddhhh', 'pjjjccclllsss', 'yyydddaaauuubbrrrvv', 'xxxrrn', 'lllzzzxxooqqa', 'yyyvyyyr'], 17))

what a goat!

Ohh okay thanks for explanation. I'll try to figure out again. thanks

You can't convert an array to null. You can return whatever you want, if your array doesn't contain something correct, just return nul. Or better, try to catch when you should return null and leave the array.

Because your function returns [NaN, NaN, NaN] when it should return null.

Why i got [Nan,Nan,Nan] instead of 'null'?

This one is hard for me
