API Management: Plugin error with large openAPI file imports

[jwefers]

Hello,

we want to expose the API of a SaaS product called commercetools through APIM for our internal APIs. We therefore create an azurerm_api_management_api with import of their openapi file (from https://github.com/commercetools/commercetools-api-reference).

The first deployment works fine. However, on running tf apply again, during refresh of the resource, we encouter this:

│ Error: Plugin error
│ 
│   with module.commercetools.azurerm_api_management_api.commercetools_graphql,
│   on ../commercetools/apim_api_declaration.tf line 9, in resource "azurerm_api_management_api" "commercetools_graphql":
│    9: resource "azurerm_api_management_api" "commercetools_graphql" {
│ 
│ The plugin returned an unexpected error from
│ plugin.(*GRPCProvider).PlanResourceChange: rpc error: code =
│ ResourceExhausted desc = grpc: received message larger than max (5727548
│ vs. 4194304)

Granted, their API file is huge. Can this be fixed or do i have to manually split up the API?
