Hello,

I'm running Centreon and trying to use the plugin hardware::hds::csu::rest::plugin  (internally developed but issue is not related to the plugin) to monitor an HDS storage system via REST. However, I'm getting the following error when executing the plugin manually:

UNKNOWN: Can't call method "add_options" on an undefined value at /usr/lib/centreon/plugins/centreon-plugins/src/centreon/plugins/http.pm line 32.

Here's the command I'm running:

perl /usr/lib/centreon/plugins/centreon-plugins/src/centreon_plugins.pl \
  --plugin=hardware::hds::csu::rest::plugin \
  --mode=alerts \
  --custommode=api \
  --hostname=xxxxxx \
  --username='localhost\xxxxx' \
  --password='xxxx' \
  --csuid='4c4c4544-0046-4210-8033-b8c04f335732' \
  --ssl-opt='SSL_verify_mode => SSL_VERIFY_NONE'

Additional notes:

• All required Perl packages (e.g. perl-libwww-perl, perl-LWP-Protocol-https, etc.) are installed.

• Basic plugin tests like check_ping or check_memory work fine using the same Perl binary and environment.

• This issue seems specific to the http.pm module inside Centreon plugins.

Any idea what might be causing $self->{options} to be undefined in this context? Is there something missing in the plugin initialization for hardware::hds::csu::rest::plugin?
