Any tips on how to further investigate root cause for:

Unexpected error: ValueError('Could not infer an active Flow context.')

Hey @Jay Sundaram -- you'll have to provide more information than this. Generally this means you did

@task
def foo():
   pass

with Flow() as flow:
    pass

foo()

Hi Jay - any chance you could post a minimum example of your flow code? Typically this error happens when tasks are called outside flow context block. For example

from prefect import task

@task
def my_task():
        print ('hi')

my_task_ = my_task()

😄

sure. thanks. pip install failed. too much STDERR to post here.

Ah do you have

git

installed?

something to do with my pip trying to pull from our CodeArtifact pypi

(that second install failed for me actually 😞 looks like that's not an easy option)

there's nothing wrong with calling a task from within a task, correct?

If you do that you need to call

task.run()

not

task()

@task()
def mytask2():
    print("task 2")

@task()
def mytask1():
    print("task 1")
    mytask2()

with Flow('myflow') as flow:
    mytask1()

reasonable?

That will break -- you'll need to call

mytask2.run()

@task()
def mytask2():
    print("task 2")
    return {'status': 'good'}

@task()
def mytask1():
    print("task 1")
    t2_results = mytask2.run()
    print(f"task 2 returned status '{t2_results['status']}'")

with Flow('myflow') as flow:
    mytask1()

ok, so like this.

Yep!

Because of the returning of some result or because of running a task from within a task?

The second one

so then why decorate it with @task? should i make just make it a regular function?

You definitely could. Decorating it with

@task

might be misleading in this case. The only reason to do so is if you intend to add it to the flow later.
