Apollo GraphQL Error – MultipartResponseParsingInterceptor.ParsingError.cannotParseResponse in SwiftUI

I'm integrating Apollo GraphQL into a SwiftUI app and encountering the following error during a query execution:

result : failure(Apollo.MultipartResponseParsingInterceptor.ParsingError.cannotParseResponse)
failed : The response data could not be parsed.

The request hits the server, but the response fails to be parsed by Apollo. I'm using the default code generation setup and executing a simple query to fetch a list of countries.

Here’s a snippet of the function:

swift Copy Edit private func fetchCountries() { switch result { case .success(let graphQLResult): if let name = graphQLResult.data?.countries { print(name) } else if let errors = graphQLResult.errors { print(errors) } case .failure(let error): print("failed : (error.localizedDescription)") } }

This is run on an iPhone 16 Pro simulator with iOS 18.2. Any idea what's causing the parsing error or how I can inspect the raw response for debugging?

Thanks in advance!
