Parsing crash on "Looking for resources needed for deployment"

[sohah]

Hi,

I am running into a crash on parsing when creating the resources. I was trying to deploy this repo after using "samlocal build" on it. Looks like this error is related only to the wrapper as I could execute "sam deploy" to trigger the original aws version without any errors.

Below is the stack trace. I am using python 3.8.

Looking for resources needed for deployment:
Traceback (most recent call last):

    parser.feed(xml_string)
xml.etree.ElementTree.ParseError: not well-formed (invalid token): line 1, column 0

During handling of the above exception, another exception occurred:

Thanks for reporting @sohah . Can you please share the relevant snippets of your SAM template here, as well as the detailed logs from the LocalStack container (with DEBUG=1 enabled)? Thanks!

Unfortunately, I do not have access to the environment that I used when this problem occurred. I am closing this issue as I am unable to reproduce it.
