API call......Expression error:1 arguments were passed to a function which expects 2

Hi ,  Kiranbrahma 

The error code means that it need two parameters in one function, the "Binary.Decompress" need two parameters:

Binary.Decompress(binary as nullable binary, compressionType as number) as nullable binary

For more information, you can refer to :

Binary.Decompress - PowerQuery M | Microsoft Learn
