Hi guys,

Executing the command "butler push" i keep getting the error

"searching for parent build signature: reading signature: wrong magic (invalid input file)

Could you add some more details? What operating system are you using? What arguments are you passing to “butler push” ?

It sounds like the file you’ve provided to butler is not a valid zip file. Please use a regular zip file when pushing, or even better you can point it to a folder directly and butler will take care of zipping it up for you
