Describe the bug

Getting methods.forEach is not a function error on amplify push since couple days (maybe week(s)).

Could be related to fix delivered as part of 4.50.0 release.
Specifically

amplify-cli/packages/amplify-provider-awscloudformation/src/utils/consolidate-apigw-policies.ts

Line 120 in fc77006

methods.forEach(method => {

Since policy management has now changed, my templates probably missing data.

3. Upgrade to 4.50.0 (or later)
4. run amplify push returns error `methods.forEach is not a function

Thank you for reporting this.

As you mentioned, there was a change in v4.50.0. The CLI now uses your API's api-params.json file to generate IAM policies. Would you mind sending that file to [email protected] and referencing this issue?

[dsinyakov]

@cjihrig thanks for prompt reply.
Sent multiple api-params.json files.
