Microsoft Translator Provider reports null error after certain period of no query
Environment: Trados Studio v2022 SP2, Microsoft Translator Provider v1.1.5.0
Symptom: According to my observation, the provider plugin reports the null reference error after 10 minutes if no translation query is made. If further query is made before the 10 minutes period concludes, the 10 minutes period will be interrupted and re-calculated. The error could be resolved by re-enabling the plugin.
Suspected cause: I suspected this relates to the authentication token of Azure API, which is valid for 10 minutes according to this page https://learn.microsoft.com/en-us/azure/ai-services/translator/reference/v3-0-reference.
