error parsing terraform json: 53:77: illegal char escape

[cncoder]

Very cool tool for importing alb, ec2 etc....

But I'm having issues importing WAF:

system env:

• provider.aws: version = "~> 2.58"

command:

terraformer-aws import aws --resources=waf --regions ap-northeast-1 --profile XXXX

2020/04/24 XX:XX:XX aws importing default region
2020/04/24 XX:XX:XX aws importing... waf
2020/04/24 XX:XX:XX Refreshing state...
.......
2020/04/24 XX:XX:XX aws Connecting....
2020/04/24 XX:XX:XX aws save waf
2020/04/24 XX:XX:XX {
  "resource": {
    "aws_waf_regex_pattern_set": {
.......
2020/04/24 XX:XX:XX error parsing terraform json: 53:77: illegal char escape

can you share line 50-55?

@sergeylanzman share the code in TF file or output?

I can be very sure that it is caused by the complicated rules in aws_waf_regex_pattern_set (my aws_waf_regex_pattern_set has a lot of backslashes "\") , because once I set deny policy about list aws_waf_regex_pattern_set, it is work!

Thanks for raising the issue!
Can confirm, backslashes are problematic. The following regex causes problems: \\ \\\ \\\\ \ \\ \\< .
