Getting "Please rebuild this data combination" on a computer but not on another one - excel

Question

This is my first try at using the Power Query... I've build a "dynamic" query in which I can change the retrieved fields as well as the filtering fields and values to be used by the query.
It's working perfectly on my computer but as soon as I try to execute it on another computer, I get the "Please rebuild this data combination" error. I saw some post saying I'll have to kind of split my query but I have not been able to figure it out.
Here is what my 2 tables look like:
Condition and fields selection
and here is my Query with the error:
Query
This might not be very elegant, but it allow me, thru a VBA script, to generate the list of fields to be retrieved and to generate the condition to be used by the SQL.
Any idea why it's not working on the other computers or how to improved the solution I'm using?
Thank you!
Notes:
Hi, all my Privacy Level are already set to 'None'.
I've tried to parametrize my code but I can't figure how. The Where condition is dynamic: it could be Where Number = "1234" but in other condition, the where might be like: 'Where Assignee = "xyz"'.
Here is a simplified example of my code:
let
Source = Sql.Database("xxxx", "yyyy", [Query=
"Select network, testid
from CM3T1M1 "
& paramConditions[Conditions]{0} &
" "])
in
Source

rebuild query, Formula.Firewall
That's a feature to prevent prevent accidentally leaking data. You can change the privacy level to ignore it

Is the dynamic query inserting those cells into the SQL query ? Report Parameters are nice for letting the user change variables without having to re-edit the query.
Parameterized native SQL queries
from: https://blog.crossjoin.co.uk/2016/12/11/passing-parameters-to-sql-queries-with-value-nativequery-in-power-query-and-power-bi/
let
Source = Sql.Database("localhost", "Adventure Works DW"),
Test = Value.NativeQuery(
Source,
"SELECT * FROM DimDate
WHERE EnglishMonthName=#MonthName AND
EnglishDayNameOfWeek=#DayName",
[
MonthName = "March",
DayName = "Tuesday"
]
)

Dynamic Power Query version of SQL Query
To dynamically generate this SQL Query
select NUMBER, REQUESTED_BY from SourceTable
where NUMBER = 404115
Table.SelectRows is your Where.
SelectColumns is your select
let
Source = ...,
filterByNum = 404115,
columnNames = {"NUMBER", "REQUESTED_BY"},
removedColumns = Table.SelectColumns(
Source, columnNames, MissingField.Error
),
// I used 'MissingField.Error' so you know right away
// if there's a typo or bug
// assuming you are comparing Source[NUMBER]
filteredTable = Table.SelectRows(
Source, each [NUMBER] = filterByNum
)
in
filteredTable
