Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/cache@v3, actions/checkout@v4, conda-incubator/setup-miniconda@v3. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Node.js 20 will be removed from the runner on September 16th, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

`auto-activate-base` is deprecated. Please use `auto-activate`. If your installer does not use the `base` environment as the default environment, also add `activate-environment: base`.

warning libmamba You are using 'pip' as an additional package manager. Be aware that packages installed with 'pip' are managed independently from 'conda-forge' channel.

ERROR: 'conda activate "layercake"' exited with code 1.

EnvironmentNameNotFound: Could not find conda environment: layercake You can list all discoverable environments with `conda info --envs`.

The 'defaults' channel might have been added implicitly. If this is intentional, add 'defaults' to the 'channels' list. Otherwise, consider setting 'conda-remove-defaults' to 'true'.
