Usage of a parameter in trigger's path of Logic App

Question

My logic app is triggered by MS Forms submission. I wanted to parameterized the URL of the form, because it will differ on various stages (dev, prod).

Here's what I have in the workflow definition:

          "triggers": {
            "When_a_new_response_is_submitted": {
              "splitOn": "@triggerBody()?['value']",
              "type": "ApiConnectionWebhook",
              "inputs": {
                "body": {
                  "eventType": "responseAdded",
                  "notificationUrl": "@{listCallbackUrl()}",
                  "source": "ms-connector"
                },
                "host": {
                  "connection": {
                    "name": "@parameters('$connections')['microsoftforms_1']['connectionId']"
                  }
                },
                "path": "@parameters('FormsUri')"
              }
            }
          },

The parameter that I would want to use is FormsUri. Its value is: /formapi/api/forms/4OkuN-CcM0CmSsBwc6kezRPsqtVlTDZAvFnsjb6skuRUNEdsdsd1ZDN1dUR0pBWwewewNVJLTi4u/webhooks (I changed part of the path before pasting it here). Unfortunately, after deployment of the logic app (which succeeds) I get the following error in the Logic App Designer:

Operation not found under connector '/subscriptions/MY SUBSCRIPTION ID/providers/Microsoft.Web/locations/northeurope/managedApis/microsoftforms'

The original value of the "path" in the trigger was: /formapi/api/forms/@{encodeURIComponent('4OkuN-CcM0CmSsBwc6kezRPsqtVlTDZAvFnsjb6skuRUNEdsdsd1ZDN1dUR0pBWwewewNVJLTi4u')}/webhooks. The URL was hardcoded.

Is it even possible to parameterize the "path"?

According to some test, it shows same error in my logic app. The code of my logic app show as:

But why not just parameterize the code of the form but not parameterize the whole url of form ? I changed the logic app as below screenshot and it works fine.
