Hi Lekhaj,
As per the shared screen captures, I think you are using the JSONDeserialize node in some action flow to deserialize the JSON string.
If you are setting a hardcoded (string) value in the expression editor, the string value must be enclosed with double quotes (""). If you are using/defining additional double quotes within the outer double quotes, you need to escape them by doubling them, i.e. you will have to include an additional double quote to escape.
So, the final hardcoded object (string) value will look something like this..
"{
""issuedDeviceReference"": ""jit_funding_card_product"",
""positionId"": ""4b7Mc6PM0n8Tu----FLF-Co-"",
""cardIssuerPartyReference"": ""4v7MX434-Czf_k---VDF-Bg-"",
""acctType"": 20,
""acctPriority: 1"",
""role"": ""personal""
}"
Hope this helps you!
Kind regards,
Benjith Sam
