AttributeError: 'Template' object has no attribute 'add_description'

Error deploy

self.cf_template.add_description("Automatically generated with Zappa")
AttributeError: 'Template' object has no attribute 'add_description'

[mikedklein]

Troposphere updated add_description toset_description along with other previously deprecated template methods. https://github.com/cloudtools/troposphere/blob/23aafdce2a7780d0e1b24700648dddd6f8d2b04b/CHANGELOG.rst#300-20210705

I think it would be as easy as updating this line to set_description once I get a workaround for the build I will try to put a PR in.

What I don't understand is why the version isn't being locked per the generated requirements.txt file. It should be locked at 2.7.0.

[mikedklein]

If you froze your requirements prior to the 3.0.0 troposphere release you should be fine. If not just add troposphere==2.7.0 to your requirements.txt to make sure to lock the version in and that should solve the issue for now.

[mikedklein]

@MayaraMacielMatos I am not sure closing this is the best. If a user today decided to use Zappa after the troposphere 3.0.0 release this could happen when they install all their dependencies.

[MayaraMacielMatos]

@mikedklein I appreciate the help, I'll keep it open

[adosaa]

Same issue here using ci/cd aws code build...partially solved using hardcoded version of troposphere==2.7.1

[mikedklein]

Looks like there is a related issue and subsequent PR we can probably safely close this issue @MayaraMacielMatos

[mapattacker]

hope it can be resolved soon since this is a simple bug to fix. thanks for pointing the resolution @mikedklein

[tongclement]

+1

[tongclement]

Thanks for the prompt response and help. I changed the code to 'set_response' myself and everything is resolved.

[DPS0340]

For pipenv users, edit Pipfile like:

[packages]
troposphere = { version = "<3.0", ignore = ["zappa"] }
zappa = "*"

What I don't understand is why the version isn't being locked per the generated requirements.txt file. It should be locked at 2.7.0.

I was also very confused by this @mikedklein , but it looks like the setup.py relies on the requirements.in, not the requirements.txt

https://github.com/zappa/Zappa/blob/master/setup.py#L10-L21

import os
import sys
from setuptools import setup
from io import open
from zappa import __version__

with open('README.md') as readme_file:
    long_description = readme_file.read()

with open(os.path.join(os.path.dirname(__file__), 'requirements.in')) as f:
    required = f.read().splitlines()

with open(os.path.join(os.path.dirname(__file__), 'test_requirements.in')) as f:
    test_required = f.read().splitlines()

setup(
    name='zappa',
    version=__version__,
    packages=['zappa'],
    install_requires=required,
    tests_require=test_required,
    test_suite='nose.collector',
    include_package_data=True,
    license='MIT License',
    description='Server-less Python Web Services for AWS Lambda and API Gateway',
    long_description=long_description,
    long_description_content_type='text/markdown',
    url='https://github.com/zappa/Zappa',
    author='Rich Jones',
    author_email='rich@openwatch.net',
    entry_points={
        'console_scripts': [
            'zappa=zappa.cli:handle',
            'z=zappa.cli:handle',
        ]
    },

And in requirements.in it doesn't specify a version for troposphere:

argcomplete
boto3>=1.17.28
durationpy
hjson
jmespath
kappa==0.6.0
pip>=9.0.1
python-dateutil
python-slugify
PyYAML
future
# previous version don't work with urllib3 1.24
requests>=2.20.0
six
toml
tqdm
troposphere
# See https://github.com/Miserlou/Zappa/issues/2036
Werkzeug<1.0
wheel
wsgi-request-logger
pip-tools

@jneves @mcrowson i wonder if there's an opportunity to get rid of the requirements.txt and just rely on requirements.in to avoid this confusion? Or alternatively update setup.py to rely on requirements.txt instead?

[clown-0726]

Still get this issue.

[clown-0726]

@mikedklein If I lock troposphere at 2.7.0, I will get another error which is error in troposphere setup command: use_2to3 is invalid..

How did you git rid of this or you didn't run into this issue?

[heukirne]

@clown-0726 , Try to lock troposphere at 2.7.1

[luistm]

I installed from master the branch. It's a temporary measured, but solved the issue for me.

If you use pipenv, you can add or replace with this line in the [packages] section inside the Pipfile:

zappa = {editable = true, git = "https://github.com/zappa/Zappa"}

[vlayusuke]

@luistm Thank you for your advice. But still the same error reappears in my environment.

• macOS Big Sur 11.6
• Python: 3.8.10
• Flask: 1.1.4
• troposphere: 3.0.0
• zappa: 0.53.0

[clown-0726]

@heukirne It doesn't work for me with 2.7.1 as well.

[qeternity]

Is this library still maintained? Just getting started and coming across a handful of bugs that are just seemingly stale.

[jottenlips]

Miserlou/Zappa#2228 Looks like this PR is the fix

[vlayusuke]

@jottenlips Thanks a lot!

[ian-whitestone]

Note, even if you pin Troposphere to 2.7.0, you'll run into a new issue that looks something like:

TL,DR: you can't install troposphere 2.7 unless you also force setuptools to be <v58

The fix for this issue is already in place on the master branch of Zappa, they just need to push a new release.

[ian-whitestone]

Miserlou/Zappa#2228 Looks like this PR is the fix

Wrong repo. As per my comment above:

The fix for this issue is already in place on the master branch of Zappa, they just need to push a new release.

[hellno]

a new zappa version was released, including a fix for this:
