Creating stream with jsonPath leads to stream validation error

[ilayaperumalg]

I have the following stream in the stream creation page:

http --server.port=9000 | transform --expression=#jsonPath(payload, '$.name') | log

and this leads to TokenizationError: Unexpected character around the expression field.

While we can add a quote around the expression value, the backend would fail if the value of the expression is quoted.
