Refresh on Power BI Service failed

Hi,

I have created BI report with API connection to datasource. Scheduled refresh on Service is worked fine few months. But suddenly the refresh stopped working and I got the error below:

When I make refresh in Power BI Desktop, everythink works ok.

I have checked if any changes was made on API side, but everythink stays like was. Also I did not make any changes in Power BI report. 

I have already tried to publish the report again, I made a Query for the Invoices table again from the beginning but nothing helped.

Does anyone have any idea what could be wrong?

My Query for Invoices table:
let
body = "grant_type=Password&resource=https://XXXXXXX.com/api/auth/token&username=XXXXXXXX&password=XXXXXXXXX",
Data = Json.Document(Web.Contents("https://XXXXXXX.com/api/auth/token/", [Headers=[#"Content-Type"="application/x-www-form-urlencoded"], Content=Text.ToBinary(body)])),
access = Data[access],
CurrentstartAtList = List.Generate(()=> [Result = try Json.Document(Web.Contents("https://XXXXXXX.com/api/received-invoices/", [RelativePath = "?created_at_after=01.01.2023&page="&Number.ToText(Page), Headers=[Authorization="Bearer " & access]])) otherwise null, Page=1],
each [Result]<>null,
each [Result = try Json.Document(Web.Contents("https://XXXXXXXX.com/api/received-invoices/", [RelativePath = "?created_at_after=01.01.2023&page="&Number.ToText(Page), Headers=[Authorization="Bearer " & access]])) otherwise null, Page=[Page]+1], each [Result]),
