Error Details

When we switched to using Browser as provider, we get the following error when running saml2aws login:

Error authenticating to IdP.: could not install driver: could not install driver: could not check if driver is up2date: could not run driver: exit status 126

Below is CLI output when running DUMP_CONTENT=true saml2aws login --debug:
