TypeError when trying to run an application on Android using Windows 10

When trying to use the ionic run Android command on my Windows 10 machine, I receive the following error;

throw new TypeError(

TypeError: Invalid data, chunk must be a string or buffer, not object

Error: Hook failed with error code 1: C:\Projects***********************\hooks\after_prepare\010_add_platform_class.js

Are there any suggestions on how to fix this issue? It doesn’t seem to affect colleagues that are using Windows 7 machines.

I found a related issue, https://github.com/driftyco/ionic-cli/issues/417#issuecomment-103531954. The suggested “solution” is to rename the after-prepare folder. I am new to Ionic, so I’m not sure what the impact of this rename will be on the application, and I am not sure if there is something else that I should be doing to fix this issue.

Renaming the folder does “fix” the issue, but it seems like this could cause issues in other areas.

I had this same error although I was building for iOS. After futilely trying to debug it, I resorted to my standard fix: I restarted fresh by creating a new project and moving my /src/ and various config files over to it. The problem did not reoccur in the new project.
