Getting looser throw specifier error when trying to mock a class which uses kj Promises

[legolas145]

Hello,
I am pretty new to Gtest and Gmock.I have a interface which has a function that returns a kj::Promise as response.I am using mock to mock that interface.

//suggestion_interface.h
#pragma once

#include <string>
#include <kj/async.h>

class ISuggestions {
 public:

  // Function to get the suggestions results from swype for a give text input
  virtual kj::Promise<Suggestions> GetAutocompleteSuggestions(std::string input) = 0;

};



//suggestion_mock.h
#include <gmock/gmock.h>

class MockSuggestions : public ISuggestions {
 public:

  MOCK_METHOD(kj::Promise<Suggestions>, GetAutocompleteSuggestions,(std::string input),(override));

};

I notice that I am getting a looser throw specifier error
/usr/include/gmock/gmock-spec-builders.h: In instantiation of 'class testing::internal::ActionResultHolder<kj::Promise >':
/usr/include/gmock/gmock-spec-builders.h:1601:20: required from 'testing::internal::FunctionMocker<R(Args ...)>::Result testing::internal::FunctionMocker<R(Args ...)>::Invoke(Args ...) [with R = kj::Promise; Args = {std::__cxx11::basic_string<char, std::char_traits, std::allocator >}; testing::internal::FunctionMocker<R(Args ...)>::Result = kj::Promise]'

/usr/include/gmock/gmock-spec-builders.h:1378:7: error: looser throw specifier for 'virtual testing::internal::ActionResultHolder<kj::Promise >::~ActionResultHolder() noexcept (false)'
1378 | class ActionResultHolder : public UntypedActionResultHolderBase {
| ^~~~~~~~~~~~~~~~~~
/usr/include/gmock/gmock-spec-builders.h:1370:11: note: overridden function is 'virtual testing::internal::UntypedActionResultHolderBase::~UntypedActionResultHolderBase() noexcept'

May I know why I am getting this error and what should I do to fix this?
