Power query : do action when a function is successfull

Hi everybody,

I'm new in Power BI and I have to use Power query to check if a custom function returns successfully or not.

I have some addresses, and I call a Bing maps function to get latitude and longitude coordinates. Sometimes this function fail because address has wrong format.
I would like to know which address is ok and which is wron, with error or success in a column to indicate the result of the search.

Here is the formula to add latitude and longitude columns (it works) :
= Table.ExpandTableColumn(Table.AddColumn(#"Colonne fusionnée insérée", "LatitudeLongitude", each try fxPointLookup(Text.Trim(Text.Replace([Address], "&", " and "))) otherwise
try fxPointLookup(Text.Trim(Text.Replace([City], "&", " and "))) otherwise fxPointLookup(Text.Trim(Text.Replace([COUNTRY], "&", " and "))) ), "LatitudeLongitude", {"Latitude", "Longitude"}, {"Latitude", "Longitude"})

So, now, I would like to add a new column, called "Error", to display "True" if the fxPointLookup call (fxPointLookup(Text.Trim(Text.Replace([Address], "&", " and ")))) failed and "False" if not.

Could you help me to do this please ?
I don't know how to get the "success" case, or a default case 😢
