Error starting Vdebug: <class 'pynvim.api.common.NvimError'>

[stephenplatz]

I've already looked at #487, #485 and #486. I just pulled f61a967, but it's frankly been a while since I've updated. I can't start a debugging session at all, even after starting vim again.

NVIM v0.3.8

Can you post the full stack trace?

[stephenplatz]

I guess I'm not sure how to provide something useful, I don't think you're looking for the vdebug logs.

[lucc]

I was hoping for a python stack trace that belongs to your headline for this issue. <class 'pynvim.api.common.NvimError'> looks like the type of an exception that I assumed was thrown.

Maybe you can also give exact steps what to do to reproduce this (php ini setting for xdebug, nvim command line, steps you perform).

I'd be happy to add a python stack trace here, but the error above is just appearing in my editor.

My php.ini simply has these settings:

xdebug.max_nesting_level = 256
xdebug.show_exception_trace = 0
xdebug.collect_params = 0
xdebug.remote_enable = 1
xdebug.remote_autostart = 0
xdebug.remote_host = ${LANDO_HOST_IP}
xdebug.remote_log = /tmp/xdebug.log

I'm using vdebug in the regular way I've always done, in this case I set a couple of breakpoints, hit <F5> and wait for the debugger. It appears that when a connection is made, the above error is thrown. What's the best way to get a stack trace?

[lucc]

You can check :help VdebugLogWindow and help VdebugOptions-debug_file.

I will try to reproduce tomorrow (at my work computer).

The log window opens when the error occurs without any additional information, it's completely empty. I was going to provide the log output above, but thought that it wouldn't be helpful. I'll provide a log here, there doesn't seem to be much in it, log level 2:

Here's a screenshot for what it's worth:

I think that is the same of #403

I did a bounty for that issue https://www.bountysource.com/issues/76208208-open-the-debug-without-any-stacktrace

Upgrading my Neovim to v0.4.4 solved this and other issues for me.
