I am trying to type a JSON string.

There should be some way to print the { literal.
I am using a workaround: .type('{{} \"key\": \"value\"{{}}{leftarrow}{backspace}
Cypress: 2.1.0
OS: Linux x86_64 (Ubuntu 16.04)
Browser: Google Chrome 62.0.3202.89
Can you try this?
.type('{{}key:value}')
{} works find. Prosti gospodi...
