Google Translate API error with using Glossaries

[DuncanLin]

Hello, I've been testing the Google Translate API v3 and importing glossaries for translation. When I create a glossary and translate using the following languages

"languageCodes": [
      "ja",
      "en",
      "ta",
      "ne",
      "si",
      "mn",
      "km",
      "uz",
      "ur",
      "ms",
      "lo",
      "ky"
    ]

 I encounter this error: "Unsupported language pair.; Failed to initialize a glossary." Are there any languages that are not supported for glossaries?

My translate source language is JA and target language is those languageCodes language

Anyone face the same issue with these language?
