The Question

I have an async class method defined like

export class ProjectResources {
    ...
  public static async createProjectResources(
    props: ProjectResourcesProps
  ): Promise<ProjectResources> {
    // Some more async calls here.
  }
}

That is producing jsii.errors.JSIIError: createProjectResources is an async method, use "begin" instead when it is executed in python.
Is there any way I should be defining or using async methods in python differently?

The TS code compiles to Python and packages without any errors.

Looking at the generated files, it looks like the static keyword is causing the invocation to use sinvoke instead of ainvoke.

I'm running into this same issue. Did you ever find a solution?

Run into the same issue as well, I cannot find any instruction to tell me how to use this begin.
