Rest API issues

I am getting the error: Unrecognised token ‘LGOF’ was expecting (‘true’, ‘false’ or ‘null’)\n

Has anybody seen this issue before? I am receiving data from REST get API, transforming the data using a mapper and then hitting a POST API which is an IP address of a router which is then forwarding to an SQL database. This is not an error from the application, this is something that is relevant to Snaplogic. Code is as follows:
[

{

“anprRequest”:{

“updateDatabase”:{

“record”:{

“Forename”:

“Ryan”

“Surname”:

“Coram”

“Plate”:

“DE69LPO”

“valid_From”:

“22/11/2019 00:00:00”

“valid_To”:

“22/11/2019 23:59:00”

}

}

}

}

]
