Way to access IFR New Issue Monitor through Eikon Data API?

Thanks for pointing me here. Trying to use the same string as in the tutorial in get_news_headlines

Product:IFREM AND Topic:ISU AND Topic:EUB AND (\"PRICED\" OR \"DEAL\")

gives me the following error:

Error code 500 | Backend error. Failed to deserialize backend response. Expected valid JSON. Error: invalid character 'i' looking for beginning of value.

But just "Product:IFREM" returns articles for me.

Has the query format changed since or is there just an issue? Using Eikon Data API proxy on Mac.

--UPDATE

Removing quotes gives results:

q = "Product:IFREM AND Topic:ISU AND PRICED OR DEAL"
