I have configured saml2aws on my new macbook pro M1 chip, and when trying to login into aws using following command getting this error:

command:

saml2aws login --session-duration=43200 --username=<email id> --mfa='DUO' --duo-mfa-option='Duo Push' --skip-prompt  --force --role='arn:aws:iam::<account>:<role>'

Error:

What I did to make it work is to comment

--mfa='DUO' \
--duo-mfa-option='Duo Push' \
--skip-prompt

then run it again, write password and chose DUO from the list. After successful login I uncomment it and it works again.

Is this the fix?

@mapkon did not work.
What work for me is

saml2aws login

after entering credentials and role selections and have run the following and it is working but the issue is still here when I ran the following command for the first time in a day. So daily I need to run saml2aws login the first time every day and after that following command works without any issue:

saml2aws login --session-duration=43200 --username=<email id> --mfa='DUO' --duo-mfa-option='Duo Push' --skip-prompt  --force --role='arn:aws:iam::<account>:<role>'

The issue still exists I have tried:

What I did to make it work is to comment

--mfa='DUO'
--duo-mfa-option='Duo Push'
--skip-prompt
then run it again, write password and chose DUO from the list. After successful login I uncomment it and it works again.
