The .json file (JSON to Features) cannot be converted with the conversion tool. ERROR 999999

While one of the .json files I obtained from the same browser website source is converted with the (JSON to Features) tool without any problems, the other cannot be converted. Since I don't know Python, I didn't know what to do. There are differences that I see when I open both files with notepad. One starts with

[{"type":"FeatureCollection","features":[{"type":"Feature","geometry":{"type":"Polygon","coordinates"]

while the other one starts with
[{"features It starts as ":[{"type":"Feature","geometry":{"type":"MultiPolygon","coordinates"]

and on the error screen of the file that I could not convert, "The table was not found." I'm getting a warning. Also:

@EfeÇağatayŞanlı - are you using the ArcGIS Maps SDK for JavaScript, or ArcGIS Pro for this issue? It looks like an ArcGIS Pro error message, which would best be reported to Technical Support, or posting here: https://community.esri.com/t5/arcgis-pro-questions/bd-p/arcgis-pro-questions
