Error uploading custom module

I am trying to upload custom module on Ignition but I get this error:
Error loading module “testing-Ignition-Module-unsigned.modl”: exception parsing “module.xml”
See log for details.
and in the log:
java.lang.Exception: Error loading module “testing-Ignition-Module-unsigned.modl”: exception parsing “module.xml”
Caused by: java.lang.IllegalArgumentException: Invalid version: “1.0”

I tried changing versions but nothing seems to be working. What could be the problem?

Seems there is something wrong with your module.xml file… can you attach the module you build or module.xml file?

I’m pretty sure your version number must have three components. Try “1.0.0” instead.
