I've got a very strange issue with Azure Cognitive Search. Soms months ago, I've created an Azure Cognitivie Search instance on our test subscription. When I query in the Search Explorer for
*&speller=Lexicon&queryLanguage=NL-NL, I successfully receive a list of search results.
Today I created an instance of Azure Cognitive Search on our production environment with the same ARM Template and exactly the same Data Source, Indexer and Index. When I run the same query as above on this instance, it returns this error:
Parameter 'speller' is only supported for search services created on or after 2019-01-01.
It is a pretty clear error... except that I created the instance a few minutes before! I didn't even had access to the subscription in 2019. I've recreated the whole instance, but it keeps throwing me this error.
Does anyone have the same issue and probably a workaround?
Update: It looks like this problem only appears when I create a free plan instance in the production subscription. The free instance on the test subscription works fine and a Basic plan on production also works.
