I have a bug in my snapcraft plugin which causes it to crash. Snapcraft shows me this: Sorry, an error occurred in Snapcraft. We would appreciate it if you anonymously reported this issue. No other data than the traceback ('/tmp/tmpw4id89ag/trace.txt') and the version of snapcraft in use will be sent. Would you like to send this error data? (Yes/No/Always) [no]: That's nice, but it would be even better if it actually showed me the traceback. Perhaps like this: Sorry, an error occurred in Snapcraft. Here is the traceback: Traceback (most recent call last): File "/snap/snapcraft/2496/bin/snapcraft", line 11, in <module> load_entry_point('snapcraft==3.1', 'console_scripts', 'snapcraft')() File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/cli/__main__.py", line 81, in run run_snapcraft(prog_name="snapcraft") File "/snap/snapcraft/2496/lib/python3.5/site-packages/click/core.py", line 722, in __call__ return self.main(*args, **kwargs) File "/snap/snapcraft/2496/lib/python3.5/site-packages/click/core.py", line 697, in main rv = self.invoke(ctx) File "/snap/snapcraft/2496/lib/python3.5/site-packages/click/core.py", line 1066, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File "/snap/snapcraft/2496/lib/python3.5/site-packages/click/core.py", line 895, in invoke return ctx.invoke(self.callback, **ctx.params) File "/snap/snapcraft/2496/lib/python3.5/site-packages/click/core.py", line 535, in invoke return callback(*args, **kwargs) File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/cli/lifecycle.py", line 253, in snap _execute(steps.PRIME, parts=[], pack_project=True, output=output, **kwargs) File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/cli/lifecycle.py", line 110, in _execute project_config = project_loader.load_config(project) File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/internal/project_loader/__init__.py", line 47, in load_config return Config(project) File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/internal/project_loader/_config.py", line 242, in __init__ build_tools=self.build_tools, File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/internal/project_loader/_parts_config.py", line 52, in __init__ self._process_parts() File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/internal/project_loader/_parts_config.py", line 71, in _process_parts self.load_part(part_name, plugin_name, properties) File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/internal/project_loader/_parts_config.py", line 186, in load_part definitions_schema=self._validator.definitions_schema, File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/internal/pluginhandler/_plugin_loader.py", line 41, in load_plugin plugin_name, plugin_class, part_schema, definitions_schema File "/snap/snapcraft/2496/lib/python3.5/site-packages/snapcraft/internal/pluginhandler/_plugin_loader.py", line 112, in _validate_pull_and_build_properties part_schema, definitions_schema, plugin.schema() File "/root/project/snap/plugins/my_plugin.py", line 15, in schema schema['required'].append('my-property') KeyError: 'required' We would appreciate it if you anonymously reported this issue. No other data than the traceback and the version of snapcraft in use will be sent. Would you like to send this error data? (Yes/No/Edit/Always) [no]: Note that I added the option to 'Edit' which would launch an editor with the traceback so someone could remove any awkward information and then send it.
