    LON,

    Change your code as follows. And maybe you would need to change List.IsEmpty(content) part in the following code to List.IsEmpty(Source) or List.IsEmpty(body), you can test it.

    let

Source = Json.Document(Web.Contents("https://xxxxxxxxxxxxx", [Headers=[zzzzz="xxxxxx"]])),
body = Source[body],
content = body[content],
#"Converted to Table" = Table.FromList(content, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
Table1=Table.FromRecords({
        [Column1 = ""]
        
    }),
     result= if List.IsEmpty(content) then Table1 else #"Converted to Table" 
in
     result

This is not working. In my case from Source = Json.Document(Web.Contents("https://api.abcxyz.com/v2/data_check?request_key=abcxyz12345")) is not giving any results. 

is there any way to handle the no result so that we can avoid the "DataFormat.Error: We reached the end of the buffer." on the PowerBI model refresh. 

 

we can show blank data.
