[rancid] Issue with Huawei device NE40E-M2K-B

[absolutely_free at libero.it]

Hi,
I am using:

$ bin/rancid -V
rancid 3.6.2

$ /usr/bin/expect -v
expect version 5.45

$ /usr/bin/perl -v

This is perl 5, version 24, subversion 1 (v5.24.1) built for x86_64-linux-gnu-thread-multi

$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 9.12 (stretch)
Release:        9.12
Codename:       stretch

I am trying to get configs from Huawei devices (NE40E-M2K-B).
I used these scripts:

https://github.com/ssinyagin/rancid-ssi/blob/master/bin/hulogin.in
https://github.com/ssinyagin/rancid-ssi/blob/master/bin/hurancid.in

with very little changes (only shebang).

I can successfully login with hulogin script but "display version" never completes:

rancid at rancido:~/bin$ ./hulogin  -t 5 -c"display version" c1-huawei
c1-huawei
spawn ssh -c aes128-ctr -x -l root c1-huawei

While hurancid -d gives me this:

rancid at rancido:~/bin$ ./hurancid -d c1-huawei
Can't use 'defined(%hash)' (Maybe you should just omit the defined()?) at ./hurancid line 46.

Any suggestion?
Thank you!
