Update Docs to Specify Version (or Range) for serverless

[alexandermichels]

When reproducing the steps to deploy the app, I ran into the following error while running "sls deploy":

✖ The Serverless version (4.1.12) does not satisfy the "frameworkVersion" (3) in serverless.yml
ServerlessError2: The Serverless version (4.1.12) does not satisfy the "frameworkVersion" (3) in serverless.yml

As the error implies, uninstalling serverless and installing a 3.* version solved the problem (in my case npm install -g [email protected]). I don't know enough about serverless to know if any 3.* works though.

@alexandermichels : my Serverless is on 3 as below:

And in Serverless.yml, we have

# You can pin your service to only deploy with a specific Serverless version
# Check out our docs for more details
frameworkVersion: '3'

So far, version 3 works well. I think after I finish the last deployment, Serverless will probably upgrade its version. You can continue with version 3 since it has proven to work fine. We can consider upgrading the Serverless version in the future if needed.

I'm not requesting an upgrade of the version, just asking to specify the version in Step 1 here: https://github.com/healthyregions/spatial-access?tab=readme-ov-file#deploy-backend-with-serverless to make the workflow easier to reproduce.

Oh I see, yes please go head with version 3 then
