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)

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 ""

? 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.
