Hello, the bug still happens in aws-amplify/cli@12.8.2

java version:

openjdk version "18" 2022-03-22
OpenJDK Runtime Environment (build 18+36-2087)
OpenJDK 64-Bit Server VM (build 18+36-2087, mixed mode, sharing)

Node v18.13.0.

If I downgrade to aws-amplify/cli@10.6.2 it’s works.

It seems that this problem is back on versions 10.7.x Downgrading to version 10.6.2 works: npm install -g @aws-amplify/cli @10.6.2

@akinwol @kolodi @lazpavel … 8.5.1 has fixed this issue for me!

dwamianm on Jun 18, 2022

Tried 8.4.0 and the issue is still there. Downgrading to 8.0.2 seems like the only fix for now.

akinwol on Jun 9, 2022

The issue is still present in 8.2.0. Downgrading to 8.0.2 solved it for now.

Getting the same issue using Chrome for Mac Version 100.0.4896.127 (Official Build) (x86_64). Also tried Safari. The developer console gives “Error: Error when generating OIDC token: Buffer is not defined”

Do I need to downgrade to 10.6.2 and my java version as @Bandisa mentioned above?

I have this issue in 11.1.0 Reverting to 10.6.2 resolved it.

I have opened https://github.com/aws-amplify/amplify-category-api/issues/1427, since this is a closed issue

I can confirm that my schema is available in version 9.1.0

AlirezaNikkhah1375 on Jul 8, 2022

I can confirm that it is also working in 9.0.0.

Hey @jw4949 👋 I was able to reproduce this on the latest version of the CLI (8.0.3), and it appears we are not able to view the schema nor are we able to update auth, however queries & mutations appear to be working as expected despite the lack of explorer functionality. Downgrading to 8.0.2 mitigates this issue

8.0.2

8.0.3

Marking as a bug 🙂
