<p>Hello Michele,</p>
<p>the problems could be solved and are already upsteam. They'll be
deployed in a few days. To work properly, you have to set the
first three parameters as in the example below. threaded and use_reloader
can be any combination but I found out, that when threaded is set
to False and use_reloader set to True, an exception is cought but
after that the reloader isn't informed about the broken thread.
You need to change a file to trigger the reloader, otherwise the
server doesn't respond anymore. That's not an issue by Eric and
can be observed on other debuggers too.</p>
<p>app.run(debug=True, passthrough_errors=True, use_debugger=False, threaded=True|False,
use_reloader=True|False)</p>

<p>Hello Michele,</p>
<p>thanks for the report! I've implemented the new debug_monitor
and did some first investigations.</p>
<p>At least I found a solution which "works". It might be a
workaround till the final soulution is available. Just add
threaded=False as additional parameter, so you get</p>
<p>app.run(debug=True, threaded=False, passthrough_errors=True,
use_debugger=False, use_reloader=False)</p>
<p>I hope this helps for the moment.</p>

<div>Hello,</div>
<div>I'm trying to use Eric to debug a simple Flask
application, but I think that there are some conflicts with
Eric and Flask's internal debugger.</div>
<div>I'm trying all the combination found on Eric debugger
("report all exceptions", "multiprocess" and so on) and also
all the Flask applications debug / reload and so on
parameters founds on: <a
href="https://flask.palletsprojects.com/en/stable/debugging/"
class="moz-txt-link-freetext" moz-do-not-send="true">https://flask.palletsprojects.com/en/stable/debugging/</a></div>
<div><br>
</div>
<div>But:</div>
<div>- with Flask debug (reload enabled by default), Eric
cannot follow the children spawn (this is the last problem
if Eric would be able to debug Flask error, but with Flask
reload enabled, Eric return with a "app.py has terminated
with exit code 0")</div>
<div>- with Flask debug on and reload not enabled
(use_reloader=False) without "report all exceptions" on
Eric, Eric starts but not catch exception and has
a KeyError (see below), and I see the errors only Eric
terminal</div>
<div>- with Flask reload disabled without Eric breakpoint and
without errors, all goes well, but with breakpoints or
errors:</div>
