awk runs and produces output but with error

When I run the awk below, I get an error message

Code:
awk -v OFS='\t' '$(NF-1)=="Benign" || ($(NF-2) OFS $(NF-1))=="Likely Benign" {$(NF)=$(NF-2) OFS $(NF-1)} {print $0 }' input
awk: cmd. line:1: (FILENAME=VUS FNR=8) fatal: attempt to access field -1

input
Code:
Chr    Start    End    Ref    Alt    Func.refGene    AAChange.refGene    PopFreqMax    CLINSIG    Classification

The code ran with no error before I added $7 and I also used the below awk to see what NF equals, but am not able to correct the error:

Code:
awk 'NR==1{for(i=1;i<=NF;i++){print "Number of field in terms of NF is--> NF-" NF-i", value is-->" $i}}' file.txt
Number of field in terms of NF is--> NF-9, value is-->Chr
Number of field in terms of NF is--> NF-8, value is-->Start
Number of field in terms of NF is--> NF-7, value is-->End
Number of field in terms of NF is--> NF-6, value is-->Ref
Number of field in terms of NF is--> NF-5, value is-->Alt
Number of field in terms of NF is--> NF-4, value is-->Func.refGene
Number of field in terms of NF is--> NF-3, value is-->AAChange.refGene
Number of field in terms of NF is--> NF-2, value is-->PopFreqMax
Number of field in terms of NF is--> NF-1, value is-->CLINSIG
Number of field in terms of NF is--> NF-0, value is-->Classification

Thank you especially @RavinderSingh13 Smilie

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
