Renaming Special character key with Jolt transform

December 5, 2022

Please help me write the jolt spec to rename the key with a special character "@". When I place "@" in jolt spec, it is not working. I am getting the below error

Error running the Transform.

JOLT Chainr encountered an exception constructing Transform className:com.bazaarvoice.jolt.Shiftr at index:0.

Invalid key:Company@1 can not have an @ other than at the front.

Please help in resolving this.
