Hi @captainsidd,

Thanks

I was facing the same issue, I use a shared API Gateway resource through different services and was getting the exported API Id with Fn::ImportValue. I managed to merge these changes to version 3.3.1 manually and everything is working as expected. Thanks.

Hi all, this has just bitten me to. The PR has been open for five months and it now has conflicts. Can we work to get this deployed?

@sampsasaarela if you could update your PR so that @aoskotsky-amplify, @jconstance-amplify or someone else with write access can merge it?

I'm sure the time to review and merge will be far less than the time that 14 or more people have spent hunting this down.

Thanks everyone! (Especially @sampsasaarela for getting a patch ready!)

Update: It's 2020. This PR has been open for a year and five months!
