Delay a web query before calling it

[WorkHard]

Hi, I'd like to delay a query from accessing the web content for 10 seconds.

Here's my current query:

let
    Source = Csv.Document(Web.Contents("httpsURL"),[Delimiter=",", Columns=5, Encoding=1252, QuoteStyle=QuoteStyle.None]),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
in
    #"Promoted Headers"

and here's how I think it would work:

let
    Source = Function.InvokeAfter(Csv.Document(Web.Contents("httpsURL"),[Delimiter=",", Columns=5, Encoding=1252, QuoteStyle=QuoteStyle.None]),#duration(0,0,0,10)),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
in
    #"Promoted Headers"

This gives me an error: "We cannot convert a value of type Table to type Function".

Again, I'd like to enter this delay before accessing the web source.

Hi @WorkHard ,

PowerQuery M is not my strong suit but I recalled a similar question. I think your M should work like this:

let
    Source = Function.InvokeAfter( () => Csv.Document(Web.Contents("httpsURL"),[Delimiter=",", Columns=5, Encoding=1252, QuoteStyle=QuoteStyle.None]),#duration(0,0,0,10)),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true])
in
    #"Promoted Headers"

Kind regards
