HttpResponseException: 404 Help

Hey guys,

I am a Coop and as a side task, my boss asked me to help dig around to find a solution for this problem. Only her laptop or app is affected. I can open it just fine. I’ve heard it could be a corrupted file but I am just putting this out there cause why not. If it is a corrupted file, any ideas how to fix it? I have attached a screenshot of the error below. Thank you very much for your time.


Can you tell us what version of Ignition you’re launching a project against? And what version of the client launcher, assuming that’s what we’re looking at?

It is Ignition 8. Client Version 1.0.15. I am unaware of the version my boss has installed and she is not currently in office today

I am getting the same error on a client after a Gateway restart. Gateway version 8.0.16 and Vision Client Launcher 1.1.0-rc2 for Windows. Clicking Retry does not fix the problem.

Clearing the .ignition/cache folder also does not fix the issue. Any suggestions?

Launch failed on step "StartupStep" with error:
com.inductiveautomation.ignition.client.launch.steps.HttpResponseException: 404: Unable to get project init descriptor
	at com.inductiveautomation.factorypmi.application.runtime.ClientLaunchHook.downloadProjectInitDescriptor(
	at com.inductiveautomation.factorypmi.application.runtime.ClientLaunchHook.setup(
	at java.base/ Source)

Update - All clients are having this error after the Gateway restart but only for one particular Project. Other Projects are working fine.

Found the issue. We renamed a Project but did not update the vision-client-launcher.json file with the correct “project”: key after the rename.
