Hello Team,

I am parsing register value using debug and using when condition to print particular matching value. While doing that am getting below error. some of the register value doesn’t have “volume\_attachments” variable due to that the when condition is failing. I want to ignore this error how can I do it. Could you please help me on this. Thanks in advance.

fatal: [localhost]: FAILED! =\> {“msg”: “The conditional check ‘item.volume\_attachments | length == 0’ failed. The error was: error while evaluating conditional (item.volume\_attachments | length == 0): ‘dict object’ has no attribute ‘volume\_attachments’\n\nThe error appears to be in ‘/var/lib/home/s’: line 33, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - debug:\n ^ here\n”}

Regards,  
Jegan A
