Known Bug with ParallelCluster/Flask

[hahnd]

Greetings,

If you have installed WRF Cloud in the last couple of weeks, you might be seeing a bug that prevents you from starting a cluster. We just discovered this today and will be looking into a fix.

The problem has been reported to the aws-parallelcluster development team here:
aws/aws-parallelcluster#5244

If you need a fix sooner, here are the steps:

Download our pre-packaged lambda layer zip file:

> wget https://www.wrfcloud.com/lambda_layer.zip
> shasum -a 256 lambda_layer.zip 
01565c9ab0f5ce624ed9c568122834d63ae669c90d352e41723b68d132b06ea5  lambda_layer.zip

Use this to update your production_python_deps Lambda Layer.

Then update your production_wrfcloud_handler Lambda Function to use the latest version of the layer.

Please ask here if you have any questions on the details of these steps.
