Azure Logic App integration with SAP over RFC Function module

Question

I'm trying to automatize process using Logic Apps -> On-premises data gateway -> SAP system.
I think I have a problem with metadata or cache.

Scenario:
I stopped developing solution on wednesday about 23 (it didn't work), I didn't change anything inside and started to work on thursday(today) about 12. I had to remind myslef what kind of bug it was so i ran this logic app and suddenly it worked fine. I've been using element [RFC] Call function in SAP in logic app with input RFC parameters:

<?xml version="1.0" encoding="utf-8"?>
<ZFM_MGR_RFC xmlns="http://Microsoft.LobServices.Sap/2007/03/Rfc/">
      <INVOICE_ID>@{outputs('Invoice')['InvoiceId']}</INVOICE_ID>
</ZFM_MGR_RFC> 

ABAP FM:

FUNCTION ZFM_MGR_RFC
  IMPORTING
    VALUE(INVOICE_DATE) TYPE STRING OPTIONAL

  DATA: ls_test TYPE zasd_test.
  ls_test-mandt = sy-mandt.
  ls_test-dates = sy-datum.

  INSERT zasd_test FROM ls_test. 

So... I decided to enhance my FM in ABAP with another importing parameters. I added f.e. CUSTOMER_NAME parameter (string) and input parameter in logic app. Suddenly I have an error - there's my [RFC] Call function in SAP response:

{
    "statusCode": 400,
    "headers": {
        "x-ms-request-id": "7c4b6579-956d-4816-b988-73ad72d2962e",
        "Strict-Transport-Security": "max-age=31536000; includeSubDomains",

        "x-ms-connection-gateway-object-id": "7ebb3fec-1964-41ff-b45b-b97e71c65616",
        "Timing-Allow-Origin": "*",

        "Date": "Thu, 15 Jul 2021 21:37:41 GMT",
        "Content-Length": "202",
        "Content-Type": "application/json"
    },
    "body": {
        "error": {
            "code": "GeneralBadRequest",
            "message": "Failed to process request. Error details: 'Parameter: 'CUSTOMER_NAME' not found in the function metadata.'.",
            "target": ""
        }
    }
}

It looks like Logic Apps/On-premise gateway has metadata of function module saved somewhere and refresh it not very often. How can I change it?

Thanks in advance.
