Online playground doesn't seem to work

[PoignardAzur]

I tried to input the following into the online playground at https://codegeex.cn/playground:

// We have a list of recipes with the given format:
// - Line 0: integer N which is the number of recipes in list
// - Line 1-N: a recipe, with three ingredients separated with spaces
//
// Given the recipes as input, write the number of unique ingredients on standard output
//
// EXAMPLE INPUT:
// 3
// tomato mozzarella ham
// tomato pineapple ham
// cream pepper mushroom
// EXPECTED OUTPUT:
// 7

const input = `
3
tomato mozzarella ham
tomato pineapple ham
cream pepper mushroom
`.trim().split('\n');

CodeGeeX proposed completions along the lines of:

... [ [ syntax syntax. syntax. syntax. syntax. syntax. syntax. syntax. syntax. syntax. syntax. syntax. syntax. syntax.

Not sure if this a model problem or just an API problem.
