App went to sleep, can't wake it up

My app is deployed in the Community Cloud. It was working fine until a few days ago. Then it went to sleep over the weekend due to lack of activity. It is hosted on a private github repository. Here is the requirements file:

name: base

  • defaults
  • conda
  • python=3.9
  • console_shortcut
  • conda-env
  • conda-build
  • conda-verify
  • _ipyw_jlab_nb_ext_conf
  • anaconda-navigator==2.3.2
  • navigator-updater
  • spyder
  • pandas
  • openpyxl
  • matplotlib
  • xmltodict
  • nuitka
  • pyinstaller
  • plotly
  • scipy
  • streamlit
    prefix: C:\Anaconda

Here is the error message:

An unexpected error has occurred. Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.

Example: conda --no-plugins install <package>

Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.

Example: CONDA_NO_PLUGINS=true conda install <package>

[16:21:45] ❗️ installer returned a non-zero exit code
[16:21:45] ❗️ Error during processing dependencies! Please fix the error and push an update, or try restarting the app.
[16:23:25] ❗️ Streamlit server consistently failed status checks
[16:23:25] ❗️ Please fix the errors, push an update to the git repo, or reboot the app.

Any ideas what happened and how to resolve?

Hi @brisid
The error message seems to be due to library installation issues via Conda.

I understand, but I am wondering what happened since I didn’t change anything and the app was working correctly a few days ago before going to sleep.
