extra backward slash along with quotes on jsonencode a json array object - json

Question

In terraform,I am trying to make a PUT call via curl command using null_resource and executing the command in local_exec provisioner. The body of the request is json array.
The command expects the data to be in string format. I have the data as tuple in locals. I am using jsonencode to serialize the tupple to a string and pass to curl. But on jsonencode, the string formed has an additional \ prefixed before each " in json string.
eg. expected json string is:
"[{"key-1" : "value-1", "key-2": "value-2"}]"
But after jsonencode, the formatted string is as follows:
"[{\"key-1\" : \"value-1\", \"key-2\": \"value-2\"}]"
additional backslash is added along with quotes.
Because of the malformed request body, the API returns Bad Request response.
How can we correctly serialize the tupple/list to correct json string in Terraform and pass to curl command?
This is my null_resource:
resource "null_resource" "call_API" {
for_each = { for x in local.array: x.name => {
name = x.name
vars = jsonencode(x.vars)
} }
provisioner "local-exec" {
command = <<EOF
curl -X PUT ${var.url} -d ${each.value.vars} -H 'Content-Type:application/json' -H 'Authorization:${local.bearer_token}'
EOF
}

I think I understand that you want to pass this variable
"[{"key-1" : "value-1", "key-2": "value-2"}]"
You tried to use EOF?
You can do something like that
variable "body" {
type = "string"
}
variable = <<EOF
"[{"key-1" : "value-1", "key-2": "value-2"}]"
EOF
Or with EOT, honestly I don't remember which one work
EDIT:
If the json is not static and you receive it from other module or others, you can try to expand the variable inside the EOFs
body = <<EOF
${var.json}
EOF
