Specified container do not exist when running logic app to copy blobs from one container to other

I am getting this strange issue where on copying blobs from one storage account to other, the content type of blob changes which I believe is failing my logic app.

So in Storage A, I have a blob with content type as application/octet-stream which a .txt file, if I copy this file to my storage account B using storage explorer, the content type changes to text/plain; charset=utf-8

Problem now I am having is with application/octet-stream as I designed my logic app with my storage explorer B and now changing the connection string to Storage Explorer A , my logic app is returning application/octet-stream which i believe is giving me error as specific container not found in logic app Copy Blob activity.


So i would like to know why this behavior. Is there some way we can fix the content type of a storage account?
