Why this json string cannot be parsed?

{
    "contents": "While \u003Ca href=\"https://www.pcgamer.com/uk/search/?searchTerm=team+fortress+2\" "
}

using JSON

json = """
{
    "contents": "While \u003Ca href=\"https://www.pcgamer.com/uk/search/?searchTerm=team+fortress+2\" "
}
"""

JSON.parse(json)

Then throw a error:

ERROR: Expected ',' here

                    ^

Why? I think this is a validated json string.

This is just julia string parsing. The \" in your string literal resulted in just a ".
