Unable to create change request using new template

[hkshetty]

Dear Team,

As an admin, I have created two new templates and provided access to team to access the change mgmt module in OTRS. One thing I have noticed that when any of us try to create a new change using the new templates, we get the following error:

Was not able to create change from template!

Error details:
----------------
Backend ERROR: OTRS-CGI-10 Perl: 5.18.2 OS: linux Time: Tue Oct 13 07:36:49 2015 Message: Could not create change! RemoteAddress: 180.87.13.234 RequestURI: /otrs/index.pl Traceback (4115): Module: Kernel::System::ITSMChange::Template::ITSMChange::_ChangeAdd Line: 386 Module: Kernel::System::ITSMChange::Template::ITSMChange::DeSerialize Line: 304 Module: Kernel::System::ITSMChange::Template::_CreateTemplateElements Line: 1202 Module: Kernel::System::ITSMChange::Template::TemplateDeSerialize Line: 1120 Module: Kernel::Modules::AgentITSMChangeAddFromTemplate::Run Line: 227 Module: Kernel::System::Web::InterfaceAgent::Run Line: 996 Module: ModPerl::ROOT::ModPerl::Registry::opt_otrs_bin_cgi_2dbin_index_2epl::handler Line: 41 Module: (eval) (v1.99) Line: 206 Module: ModPerl::RegistryCooker::run (v1.99) Line: 206 Module: ModPerl::RegistryCooker::default_handler (v1.99) Line: 172 Module: ModPerl::Registry::handler (v1.99) Line: 31

Please find attached the error message for more details.

Note: Please be informed that the we are able to create CRs using old templates but not the new ones. Am I missing something here.

Your advice is highly appreciated!

Regards
