Couldn't create omegaconf with AWS tokens

[igovindarajan-fincad]

AWS tokens is of the form ${Token[TOKEN.186]}. Latest omegaconf complaints as below.
omegaconf.errors.GrammarParseError: missing BRACKET_CLOSE at '.' when I try the following code:

>>> import omegaconf
>>> omegaconf.OmegaConf.create({"s3":"${Token[TOKEN.186]}"}) 

This was working fine until 2.1.0.dev19. Can this be supported in the next version. By which omegaconf latest versions can be used in AWS CDK projects/repo. Thank you!

Try escaping the dollar sign with a backslash:

>>> omegaconf.OmegaConf.create({"s3":"\${Token[TOKEN.186]}"})

For in-depth information on the omegaconf interpolation grammar, including what characters to escape and when, you can look at:

• there is a great PR Add documentation for the OmegaConf grammar #792 that will soon be merged, which updates the omegaconf docs with more details on the grammar
• You can look at the grammar files omegaconf/grammar/OmegaConfGrammarLexer.g4 and omegaconf/grammar/OmegaConfGrammarParser.g4

This includes escaped backslash while retrieving the value. Is this intended?

>>> import omegaconf
>>> conf = omegaconf.OmegaConf.create({"s3":"\${Token[TOKEN.186]}"})
>>> print(conf.s3)
\${Token[TOKEN.186]}

Check your OmegaConf version.

FYR @igovindarajan-fincad here is the behavior with OmegaConf 2.1.1

>>> conf = omegaconf.OmegaConf.create({"s3":"\${Token[TOKEN.186]}"})
>>> print(conf.s3)
${Token[TOKEN.186]}
>>> omegaconf.__version__
'2.1.1'

My bad, it works. Thanks.
