Hello, it looks like XD has issue while parsing manifest.json file. If plugin version is higher than 99 installation fails with “Cannot install Plug-in, please try again. Error code -4”.
In my case plugin version is "version": "0.7.144" and I can’t install it. If I replace plugin version to 0.7.99 everything works.
While I agree that this isn’t ideal, it is documented this way => I don’t think there’s any way to work around that, and at least for now, 99 is the maximum number any of the segments can take.
Cf. https://www.adobe.io/xd/uxp/develop/plugin-development/plugin-structure/manifest-v3/ :
Version number of your plugin in
x.y.zformat.
Version must be three segments and each version component must be between0and99.
It sounds really weird. Are there any reasons for such solution?
To be honest, I have no idea. I can ask around once the US colleagues are back from their Thanksgiving celebrations, though
