Code outline not working with RemoteFS

[cdsaenz]

First, excellent work, love the extension.

Now I'm trying to have a code outline (an indexed way to jump to method or functions, in this case, PHP) and using the RemoteFS extension to open the files directly from my hosting code-outline extension won't parse any symbols. Works locally though. Maybe there's some kind of cache that I can enable for RemoteFS? Thanks a lot!

Hi @kt474 @merav-aharoni any update on this?

It seems like the best solution, for now, is to keep using the deprecated qiskit.IBMQ module. When would functionality from there be removed completely? This would be helpful to know so that things don't start breaking unexpectedly.

There is an issue with the configuration/coupling map for simulator_extended_stabilizer - I will get it prioritized in the appropriate team

Note that "simulator_stabilizer" is also affected.

Hi @kt474, any updates on this?

I can confirm this still affects 0.7.3

from qiskit import transpile, QuantumCircuit

provider = IBMProvider()
backend = provider.get_backend('simulator_stabilizer')

@1ucian0 This needs to be fixed on the server side - there is an issue open (ntc 2451), we need to get the right backend configurations
