I'm trying to create an object and add some auto-extracted attributes. Some field names contain curly braces because our JSON data contains array structures. As the screenshot shows, the field name is facts.authorizations{}.authorization.expiry .
When implementing a Splunk search, using this field name works perfectly fine; and this is also automatically generated in the list of attributes. However, when I select this field to be added into an attribute, Splunk generates an error message stating "Field Name cannot contain whitespace, double quotes, single quotes, curly braces or asterisks", which prevents me from adding this attribute.
I wonder if this is a bug in Splunk? Should the constraints on field name be applied to the rename field name instead of the indexed field?
Please also suggest any remedy to this problem. Thanks a lot.
