Hello, I try to use ansible facts in variable file but i get below error. Anyone how any idea how can i use my variable in to the playbook fatal: [ANSIBLET01]: FAILED! =\> {“ansible\_facts”: {}, “ansible\_included\_var\_files”: , “changed”: false, “message”: “Syntax Error while loading YAML.\n found unacceptable key (unhashable type: ‘AnsibleMapping’)\n\nThe error appears to be in ‘/etc/ansible/yml/AzirPlaybooks/install/elk/elkvar.yml’: line 1, column 12, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\nhostname: {{ ansible\_hostname }}\n ^ here\nWe could be wrong, but this one looks like it might be an issue with\nmissing quotes. Always quote template expression brackets when they\nstart a value.
