Description
The code in schema.rs assumes the expression for "generationExpression" should be a valid JSON for some reason, it shouldn't, it doesn't specify this in the protocol.
The code tries to deserialize this as a JSON VALUE and fails, thus unable to open the table.
Even the unit tests wrongly assume this, see the extra escaped double quotes:
{"name":"id2","type":"integer","nullable":true,"metadata":{"delta.generationExpression":"\"id * 10\""}},]
