Let's say we've removed a Lambda Layer from the Lambda Console and are no longer able to perform operations using the Amplify CLI.

An error occurred fetching the latest layer version metadata for ""

> amplify remove function
? Choose the resource you would want to remove 10263layer58c94806 (layer)
When you delete a layer version, you can no longer configure functions to use it.
However, any function that already uses the layer version continues to have access to it.

If you run into the following error there are two steps we can take to mitigate this error that do not involve modifying/replacing the #current-cloud-backend.zip archive in your deployment bucket.

🛑 An error occurred during the push operation: /
EEXIST: file already exists, symlink '../ulid/bin/cli.js' -> '/myproject/amplify/.temp/#current-cloud-backend/function/somelayer/lib/nodejs/node_modules/.bin/ulid'

In your file explorer perform the following:

1. delete the node_modules folder of the affected layer (using the example above, rm -rf amplify/#current-cloud-backend/function/somelayer/lib/nodejs/node_modules)
