Connecting to a API (Repsly) through Power Query DataFormat.Error: We reached the end of the buffer

Hello,

I am trying to get a list of active products from an API. With the help of this post I was able to get to the code posted below. 

However on row 1302 (it should load 1311 active products) i get an error: DataFormat.Error: We reached the end of the buffer. Filtering out the error in query does nothihg. The table does not load.

 

What is this error and how do I get arounf it? Any help or direction towards the solution is greatly appreciated.

 

let
    Final = List.Generate
    (
        ()=>
        [
            Result= Json.Document(Web.Contents("https://api.repsly.com/v3/export/products/0", [Headers=[Accept="application/json"]])),
            TotalCount = 1
    

        ],
        each [TotalCount]>0,
        each 
        [
            
            Result= Json.Document(Web.Contents("https://api.repsly.com/v3/export/products/" & Text.From([Result][MetaCollectionResult][LastID]), [Headers=[Accept="application/json"]])) ,
            TotalCount = [Result][MetaCollectionResult][TotalCount]
           

        ],

        each [Result][Products]
    ),
    FinalTable = Table.FromRecords(List.Combine(Final)),
    #"Filtered Rows" = Table.SelectRows(FinalTable, each ([Active] = true)),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Packaging", "ImageUrl", "MasterProduct"}),
    #"Removed Errors" = Table.RemoveRowsWithErrors(#"Removed Columns", {"Code"})
in
    #"Removed Errors"

The string size limit is 32K.  you seem to have run into that limit.

Thank you so much for your answer! So I figure I need to "trim" what I recieve? I figure the way to go now would be to either:

1. split the call into two queries

2. call just the active products from API (not filter them later in the query)

3. call just the necessary columns (not delete them later in the query)

 

The furthest I got is with the "Active":null,  but everywhere I though to put it did not work. This are the help dictionaries which I have a very hard time putting to use:
