Hi Peter-san,
Thank you for your reply.
I compared it with the image you provided, and it seems that the query syntax itself is not the issue. While testing various things, I found that issuing a new API key and trying again resolved the error, and it is now functioning correctly.
However, since the previous API key worked fine for other queries such as entityLookup, it doesn’t seem like the API key itself was incorrect.
For now, everything is working fine with the newly issued API key, but would it be better to request an investigation just to be safe?
