ASM iRest filter not working

Try adding an escape for the "$" in the curl command.

However the following is tested this on 11.5.4+:

curl -sk -u admin:admin -X GET https://10.3.155.111/mgmt/tm/asm/policies/H7xqtWU5TfZJpeXDcC3xAA/signatures?\$filter=performStaging%20eq%20true\&\$select=name,id,performStaging | jq .
 
{
  "selfLink": "https://localhost/mgmt/tm/asm/policies/H7xqtWU5TfZJpeXDcC3xAA/signatures?$select=name%2Cid%2CperformStaging&$filter=performStaging%20eq%20true",
  "kind": "tm:asm:policies:signatures:signaturecollectionstate",
  "previousLink": "https://localhost/mgmt/tm/asm/policies/H7xqtWU5TfZJpeXDcC3xAA/signatures?$skip=0&$select=name%2Cid%2CperformStaging&$filter=performStaging%20eq%20true",
  "totalItems": 4513,
  "nextLink": "https://localhost/mgmt/tm/asm/policies/H7xqtWU5TfZJpeXDcC3xAA/signatures?$skip=0&$select=name%2Cid%2CperformStaging&$filter=performStaging%20eq%20true",
  "items": [
    {
      "selfLink": "https://localhost/mgmt/tm/asm/policies/H7xqtWU5TfZJpeXDcC3xAA/signatures/1p7RmgJSYdJTivPK7b2b6A",
      "kind": "tm:asm:policies:signatures:signaturestate",
      "performStaging": true,
      "id": "1p7RmgJSYdJTivPK7b2b6A"
    },
    {
      "selfLink": "https://localhost/mgmt/tm/asm/policies/H7xqtWU5TfZJpeXDcC3xAA/signatures/7TlZ3m1ho4uFZKhO10RVlQ",
      "kind": "tm:asm:policies:signatures:signaturestate",
      "performStaging": true,
      "id": "7TlZ3m1ho4uFZKhO10RVlQ"
    }
    ...

Filtering for "false", then "true" and again without escaping the "$":

curl -sk -u admin:admin -X GET https://10.3.155.111/mgmt/tm/asm/policies/H7xqtWU5TfZJpeXDcC3xAA/signatures?\$filter=performStaging%20eq%20false | jq .items[].performStaging | wc -l
