Importing peering sessions from router fails

[tobzsc]

Environment

• Python version: 3.6.8
• Peering Manager version: 1.3.0

Steps to Reproduce

In the UI got to Internet Exchanges and select an IX where you want to import the sessions. In the Peering Sessions tab click on the Import from Router button.

Expected Behavior

It is expected that the sessions for this exchange which are configured on this router are correctly imported.

Observed Behavior

After clicking the button the pop-up does not show the correct the prefixes (cosmetic issue). When clicking Import the import process starts correctly in background (napalm.log shows the sessions are being grabbed correctly) but the whole process seems to be stuck and does not complete.

After 10 minutes nothing has changed.
