Undefined offset when creating host prototype on host and template via API

Steps to reproduce:

1. Create template AAA
2. Create discovery rule on this template
3. Create host BBB
4. Create discovery rule on this host
5. Link template AAA to host
6. Send api request to create two host prototypes, one on host and one on template

       "method": "hostprototype.create",
       "params": [
           {
               "host": "{#HOST} prototype",
               "ruleid": "33768",
               "groupLinks": [
                   {
                       "groupid": "5"
                   }
               ]
           },
           {
               "host": "{#TEMPLATE} prototype",
               "ruleid": "35801",
               "groupLinks": [
                   {
                       "groupid": "5"
                   }
               ]
           }
       ],
   

Result:
PHP runtime error
