datasource.error: sharepoint: request failed: the remote server returned an error: (429)

Hi,

I have this follwing query which connects to a Office 365 shareporint folder. I am consuming a web service with SOAP call. Powershell makes the SOAP call and creates a subfolder by each date inside a static folder (office 365 sharepoint location) and saves the xml responses there. Each subfolder contains about 1500 xml files. I connect PQWRY to that sharepoint folder.

Following is my PQWRY which I am running on service

let
  Source = SharePoint.Files("https://xyz.sharepoint.com/teams/CapData", [ApiVersion = 15]),
  #"Removed columns" = Table.RemoveColumns(Source, {"Attributes", "Date created", "Date accessed", "Folder Path"}),
  #"Filtered Rows" = Table.SelectRows(#"Removed columns", each [Extension] = ".xml"),
  #"Removed columns 2" = Table.RemoveColumns(#"Filtered Rows", {"Extension"}),
  #"Filtered Rows1" = Table.SelectRows(#"Removed columns 2", each Text.Contains([Name], "modified-bill")),
  #"Added custom" = Table.AddColumn(#"Filtered Rows1", "Custom", each Xml.Tables([Content])),
  #"Removed columns 1" = Table.RemoveColumns(#"Added custom", {"Content"}),
  #"Inserted date" = Table.AddColumn(#"Removed columns 1", "Date", each DateTime.Date([Date modified]), type date),
  #"Filtered rows 1" = Table.SelectRows(#"Inserted date", let latest = List.Max(#"Inserted date"[Date]) in each [Date] = latest),
  #"Expanded Custom" = Table.ExpandTableColumn(#"Filtered rows 1", "Custom", {"Table"}, {"Table"}),
  #"Expanded Table" = Table.ExpandTableColumn(#"Expanded Custom", "Table", {"Table"}, {"Table.1"}),
  #"Expanded Table.1" = Table.ExpandTableColumn(#"Expanded Table", "Table.1", {"Table"}, {"Table"}),
  #"Expanded Table 1" = Table.ExpandTableColumn(#"Expanded Table.1", "Table", {"Table"}, {"Table.1"}),
  #"Filtered rows" = Table.SelectRows(#"Expanded Table 1", each [Table.1] <> null),
  #"Expanded Table.1 1" = Table.ExpandTableColumn(#"Filtered rows", "Table.1", {"Table"}, {"Table"}),
  #"Removed columns 3" = Table.RemoveColumns(#"Expanded Table.1 1", {"Date"}),
  #"Expanded Table 2" = Table.ExpandTableColumn(#"Removed columns 3", "Table", {"a", "b", "c", ----"z"})
in
  #"Expanded Table 2"

and it returns the follwoing error

datasource.error: sharepoint: request failed: the remote server returned an error: (429). (429 too many requests)

Does anyone know how to prevent this ?

Thank you in advance.

Thanks @Fowmy. The delay is added by

//adding 1second delay

X=Function.InvokeAfter(()=>SharePoint.Files(),#duration(0,0,0,1))
