Flask Blueprint not working

I have a strange situation and have no idea how to find the problem.

I have created a blueprint like this 

reportjobsmod = Blueprint('jobreports', __name__, url_prefix='/jobreports', template_folder='templates')

And I have created routes like the following in the views.py file

@reportjobsmod.route('/crc_booksdue/', methods=['GET','POST'])
def crc_booksdue():

Then I use 

action="{{ url_for('jobreports.crc_booksdue') }}"

in the template.

This all works fine with a couple more routes.

However, when I try to add the following route to my views.py

@reportjobsmod.route('/job_status/', methods=['GET','POST'])
def jobs_status():

and enter

action="{{ url_for('jobreports.job_status') }}"

in the template I get routing.BuildError

I tried changing the name of the route, I replaced it with an existing route (which worked ok in the template)

I printed out app.url_map and the jobreports.job_status is there along with the other routes.

What do I try next?

Take a look at the url_for documentation:

Generates a URL to the given endpoint with the method provided.

That's the method from your app, as spelled in the app.

Your error is from

The url_for function results in a BuildError when the current app does not have a URL for the given endpoint and values.

The endpoint parameter for the function states

endpoint – the endpoint of the URL (name of the function)

In the quickstart, there's also a mention:

To build a URL to a specific function you can use the url_for() function. It accepts the name of the function as first argument [...]
