Optional chaining does not work with typescript parser

See original GitHub issue

Prettier 1.19.1 Playground link

# Options (if any):
--parser=typescript

Input:

value.optional?.length;

Output:

SyntaxError: Expression expected. (1:16)
> 1 | value.optional?.length;
    |                ^
  2 |

Expected behavior: The code is parsed without error.

When I switch to --parser=babel, it works, the problem is only with typescript parser

Still having the issue, I’m using prettier-vscode-4.4.0

SyntaxError: Expression expected. (123:29)
  121 |   if (!stateShowUserInfoModal) return <>{modifiedChildren}</>;
  122 | 
> 123 |   if (!userNetworks && data?.networks?.getUserNetworks) {

Update : In my case, I deleted node_modules content + package-lock.json and run npm i, and it worked

Can confirm that updating prettier to the latest works
