<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-CA">I have strange a bug when using QgsVectorFileWriter.writeAsVectorFormatV2() inside a lengthy loop (30 minutes between each cycle). The first run inside the loop goes well but it crashes at the second run when trying to
write a GPKG with the error below:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA"><o:p> </o:p></span></p>
<p class="MsoNormal"><i><span lang="EN-CA">options.driverName = "GPKG"<o:p></o:p></span></i></p>
<p class="MsoNormal"><i><span lang="EN-CA">RuntimeError: wrapped C/C++ object of type SaveVectorOptions has been deleted<o:p></o:p></span></i></p>
<p class="MsoNormal"><span lang="EN-CA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">I tried with a much shorter loop and it has no problem at all writing the GPKG at each cycle. I’ll try with the now deprecated QgsVectorFileWriter.writeAsVectorFormat() to see if it makes any differences. Any idea why
it could happen? By the way, I’m defining <i>options = QgsVectorFileWriter.SaveVectorOptions()</i> just before <i>options.driverName = "GPKG"
</i> each time.<i><o:p></o:p></i></span></p>
<p class="MsoNormal"><span lang="EN-CA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">Thanks<o:p></o:p></span></p>
