An unexpected error was encountered while executing "sam sync".

Steps to reproduce:

sam sync --stack-name [my stack name] --watch
I'm running with Python 3.9.16

Observed result:

See above in description.

Expected result:

sam sync should run without error. Internal python code error in the samcli should be resolved.

keeano92 · 2024-10-21T15:24:01Z

Exact Same Error as above, have tried:
Through these steps and many others, I am still getting this error.

Thoroughly clean your environment:
Uninstall SAM CLI and watchdog:
Bash
pip uninstall aws-sam-cli watchdog

Remove any residual files: Manually delete any SAM CLI or watchdog related files or folders in your Python installation directory.
Clear pip cache:
Bash
pip cache purge

Reinstall in a fresh virtual environment:
Create a new virtual environment: Set up a brand new virtual environment to ensure a clean slate.
Install SAM CLI: Install the latest SAM CLI within the activated virtual environment.
Check for conflicting packages:
Inspect installed packages: Use pip list to see all installed packages in your environment.
Identify potential conflicts: Look for any packages that might interfere with watchdog or its dependencies.
Try uninstalling or updating: If you find any suspicious packages, try uninstalling or updating them.
Examine system-level dependencies:

System Python: If you're using the system-wide Python installation, there might be conflicts with other system packages or configurations. Consider using a separate Python installation managed by a tool like pyenv to avoid such issues.
5. (If using an IDE) Check IDE configurations:

SAM CLI settings: If you're using an IDE with SAM CLI integration, check its settings for any configurations related to SAM CLI, Python environments, or dependency management.
Disable conflicting plugins: Disable any plugins or extensions that might interfere with SAM CLI or watchdog.

Hey @keeano92, @914005, Thanks for reporting this issue! Could you try uninstalling SAM CLI and installing it again with our installers published here on the github and see if that fixes your issue? Ill look into reproducing this in the meantime

sidhujus · 2024-10-22T18:08:15Z

I am able to reproduce the issue when installing sam through pip, but it works fine when installed through our published installers.

keeano92 · 2024-10-22T18:50:20Z

@sidhujus I have done as you instructed, I uninstalled sam locally and from pip. I then installed using the MSI package and restarted VSCode so its terminal would restart. I Ran sam --version to make sure it had installed correctly and again, I am looking at this error:

I am getting errors now too for sam deploy guided, about pip packages. I am going to have to uninstall sam-cli the way you suggested and do it through pip to get my deploys up.

keeano92 · 2024-10-22T19:36:55Z

i did a modify>repair and deploy is working again. I am also going to try sync after

@sidhujus So Sam sync still does not work and provides the same error on my end, Ref:

Received the same error above while running "The Complete AWS SAM Workshop". With both commands specified below:

SAM CLI, version 1.126.0

sam sync --watch --build-image amazon/aws-sam-cli-build-image-python3.11 --use-container --stack-name sam-app

or

sam sync --watch --stack-name sam-app

Leigh-M · 2024-10-24T10:09:51Z

Same issue for me, upgraded Ubuntu to 24.04.1 LTS (Python 3.12.3)

Clean re-install of all software including SAM. sam sync runs fine but sam sync --watch throws: Error: BaseObserver.schedule() takes 3 positional arguments but 4 were given. Impacting work.

Uninstalled SAM and fresh install from AWS: https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/install-sam-cli.html issue not resolved by re-installing

stephenVertex · 2024-10-25T19:54:29Z

Seeing the same issue on macOS.

hnnasit · 2024-10-28T20:21:02Z

It looks like the issue is coming from the watchdog version bump to 5.0.3. The team is actively working on the fix. Please use the previous version SAM CLI 1.125.0 as a workaround while the team works on getting the fix out.

UPD: works if I install sam cli with pip instead of brew.

brew uninstall aws-sam-cli

pip install --upgrade aws-sam-cli
