Parse-server demo in moralis-Sdk error

Good, take the example of the moralis-sdk repository, in demo parse-server, I run the yarn install command, then yarn dev, and I get this error:

Hi @davidzuccarini

If the same command worked previously then try restarting the ts server of your code editor.

Else here is StackOverflow post about a similar error. Maybe this will work in your case.
