Sceptre delete command failing to delete templates

DevOps AWS
1

Hello guys. Can somebody help me here.
At some point of time maybe 3 -4 weeks ago sceptre delete command stopped work for all the templates that we have.
The first problem was with this:
/home/github-actions/.local/lib/python3.10/site-packages/sceptre/stack.py:465: DeprecatedWarning: template_path is deprecated as of 4.0.0. Use the template Stack Config key instead.
58
setattr(self, deprecated_attribute_name, deprecated_value)

This problem was fixed by changing template_path to
template:
path: common/ecr.yaml
as mentioned in the documentation.

And now still not possible to delete the template with the sceptre delete command and I got this error

“template is a required Stack Config.”

Ok i will give you the details
here is the command

sceptre --debug delete -y dev/us-west-2/apps/consent-v2-infra/ecrtest.yaml

7 
template:
  type: file
  path: common/ecr.yaml
stack_name: identity-profile-dev-us-west-2-apps-consent-v2-ecrtest
parameters:
  RepoName: *********************
  DataClassificationTag: "********"```


Here is the template
8

are you running in a virtual env?

9

I think no. it is running in github actions. Just set up python, install sceptre and then run sceptre delete command

10

which version of python?

11

i would try to reproduce in your local environment and debug there.

12

it’s working for us with python 3.9 in github actions…

14

it traces from debug mode.

15

ohh wait, why do you have sceptre==4.5.3 in the sceptre config file?

16

i just tried differen versions of scptre

17

No it is not ther i just messaged what version of sceptre I am using

18

sceptre==4.5.3 - this is not in the template

19

sorry, i think you are on your own. i don’t use python 3.13 and it’s not even a supported version. I would try python 3.9 to 3.12.

20

the same with python 3.9
