'How to resolve AWS Cognito SDK error: "Client <XYZ> is configured for secret but secret was not received?"
I'm asking this question because I was surprised how little information I could find from Googling. However, I was able to track down what I think is the root cause. I'll share it as an answer and see if someone is able to elaborate or provide a better explanation.
So, to clarify, I'm using the AWS JavaScript SDK for Cognito. When I tried some of the standard use cases, I received the following error:
Client is configured for secret but secret was not received
What steps can I take to resolve this?
Solution 1:[1]
Looking at the NPM package for Amazon Cognito, I notice that:
When creating the App, the generate client secret box must be unchecked because the JavaScript SDK doesn't support apps that have a client secret.
Checking my app, I found that it had a client secret. I'll try remaking the app without the secret and see if that resolves the issue.

Even i got the same error , I unchecked the "app client secret" check box during new app client creation in cognito . This solved my problem. Thanks.

I heard the same issue and I have to delete App Clients. Create a new App Clients and uncheck Generate client secret. Everything worked as expected in my code.
