Getting Cannot access package artifact

My project is using serverless-package-python-functions for packaging Python functions. I’m getting this error when trying to package my functions with warmup plugin

Error:
Cannot access package artifact at "_build/{serviceName}-{stage}-warmup-plugin-default.zip" (for "warmUpPluginDefault"): ENOENT: no such file or directory, access '{serviceName}-{stage}-warmup-plugin-default.zip'

Here is my warmup config in the custom stage

warmup:
    default:
      enabled: false
      cleanFolder: false
      package:
        individually: True
        artifact: ${self:custom.pkgPyFuncs.buildDir}/{serviceName}-${opt:stage}-warmup-plugin-default.zip

And the config at the function I want to warmup

  warmup:
    default:
      enabled: true

From my knowledge it’s looking for the zip file containing the content of .warmup folder. So I tried to add the artifact part in my warmup config, but the error still hasn’t been resolved. Would love someone could help me on this

Hi @qngdt,

The problem is here: https://github.com/ubaniabalogun/serverless-package-python-functions/blob/c8ce439fa46534716d0ebb9fa7e63298960474b0/index.js#L40-L46

The warmup plugin does a process to reset missconfigurations applied by plugins like serverless-package-python-functions, webpack, bundle, etc.

Unfortunately, because the serverless-package-python-functions plugin doesn’t override the config but modifies. The fix doesn’t work here.

The plugin should not modify functions that are not even Python to start with. Adding a check for that would be trivial.

Another solution could be for the author of the plugin to update his code so it overrides the setting, doesn’t update the actual object:

  autoconfigArtifacts() {
    _.map(this.serverless.service.functions, (func_config, func_name) => {
      let autoArtifact = `${this.buildDir}/${func_config.name}.zip`
      func_config = {
        ...func_config,
        package: {
          ...func_config.package,
          artifact = func_config.package.artifact || autoArtifact,
        }
      }
    })
  }

So, unfortunately, you need to create an issue or a PR on that plugin. And it doesn’t seem very well maintained 🙁

Hi @qngdt,

Your repo is missing the package.json, so there is no way for me to know which version of serverless or the plugins you are using.

Are you using the latest warmup plugin? You might be seeing an issue that was introduced in v6.1.0 and fixed in v7.0.1

Hi @juanjoDiaz,

I have updated the repo with the package.json files. Sorry I did not realize that the example repo from serverless doesn’t contain those. The error is still persist though.

Thanks for still keep an eye on this issue.
