Json error

Hello,

I appreciate that this may be an obsolete plugin, but it seems to be just what I need. I’m running WordPress v5.4.2. and WooCommerce 4.2.2 with Blazing Spider 1.2.0 – No Couriers appear in the drop down box for Blazing Spider on the Customer Order Screen.

The code in the plugin is

[
{
“slug”: “usps”,
“name”: “USPS”,
“url”: “https://tools.usps.com/go/TrackConfirmAction_input?qtc_tLabels1={tracking_number}”
}
]

When I validate it at JSONlint.com I get this error

Error: Parse error on line 1:
[{ “ slug”: “usps”, “
—^
Expecting ‘STRING’, ‘}’, got ‘undefined’

I’ve tried changing the brackets and the error persists. Can anyone give me some guidance here?

thanks for any help.
