I tried to write array data as json and log it into browser console and got data like this {"c2array":true,"size":[50,3,1],"data":[[[521],[273],["portal"]],[[867],[373],["tower"]],[[175],[73],["events"]],[[867],[73],["casino"]],[[174],[373],["temporal"]],[[521],[573],["arena"]],[[521],[-427],["portal"]],[[521],[973],["portal"]],[[-605],[-277],["portal"]],[[-605],[-277],["portal"]],[[1560],[-427],["portal"]],[[521],[1573],["portal"]],[[-432],[-1177],["portal"]],[[1474],[1723],["portal"]],[[2080],[-627],["portal"]],[[-1038],[1073],["portal"]],[[-1557],[-527],["portal"]],[[694],[-1927],["portal"]],[[2599],[-527],["portal"]],[[-605],[2223],["portal"]],[[1993],[2023],["portal"]],[[-2164],[823],["portal"]],[[-1557],[-1527],["portal"]],[[954],[-2477],["portal"]],[[3119],[-527],["portal"]],[[2340],[2323],["portal"]],[[-605],[2823],["portal"]],[[-865],[-2627],["portal"]],[[2080],[-2627],["portal"]],[[3639],[-627],["portal"]],[[2946],[2373],["portal"]],[[88],[3523],["portal"]],[[-2423],[1773],["portal"]],[[-2597],[-727],["portal"]],[[608],[-3477],["portal"]],[[521],[4073],["portal"]],[[4245],[323],["portal"]],[[-3203],[423],["portal"]],[[-2250],[-2327],["portal"]],[[3379],[-2077],["portal"]],[[3032],[3023],["portal"]],[[0],[0],[0]],[[0],[0],[0]],[[0],[0],[0]],[[0],[0],[0]],[[0],[0],[0]],[[0],[0],[0]],[[0],[0],[0]],[[0],[0],[0]],[[0],[0],[0]]]}
but when I try to load it into an array as json I got errors like this
what I'm doing wrong?
