If I attempt to enter new line, it results in an error:
Error: Invalid expression
on <console-input> line 1:
(source code not available)
**Expected the start of an expression, but found an invalid expression token.**
terraform console doesn’t currently support multi-line expressions. If you want to evaluate a more complex expression then it’ll often be easier to write it in a Terraform configuration file (e.g. as an output value for your root module) and then use terraform plan to see the effect of it, so you can then edit it in a full text editor.
I am also having this issue and just came across this post. I just wanted to express support for being able to use multi-line input in the Terraform console.
