Get Locations by permission code

I am getting the same error, the call is below.

https://docs.equinix.com/api-catalog/lookupv2/#tag/Lookup/operation/Get%20Locations%20by%20permission%20code

https://api.equinix.com/colocations/v2/locations

This is the error:

{

"property": "permissionCode",

"reason": "permissionCode is required"

}

]

}
