Server Issue (Detailed Information: list index out of range)

[OsvaldoSierra]

Hi DSIProuter team! I have the next issue trying to open an endpoint from the Endpoint list. I'll share PS to show the step by step:

1) Enter to "Endpoints group" 2) Just click on "Troncal remoto" (ID=13)

After click I got this error message:

Extra data: If i click the other Endpoint (ID=12) I have no problem, that Endpoint opens well.

Thank you in advance.

@devopsec Can you please look into this.

@OsvaldoSierra can you provide the following:

• os info
• dsiprouter version
• cloud environment if applicable
• steps to reproduce your issue

For the last one in particular; what state was the system in before this issue occurred.

[OsvaldoSierra]

Hi guys. Here the info:

1) OS Info: PRETTY_NAME="Debian GNU/Linux 10 (buster)" NAME="Debian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=debian HOME_URL="https://www.debian.org/" SUPPORT_URL="https://www.debian.org/support" BUG_REPORT_URL="https://bugs.debian.org/"

2) DSIPRouter version: 0.70

3) Cloud enviroment: Huawei cloud (Hiperstack)

4) Just click on "Endpoint Groups" (Left menu) => Click on a Endpoint called "TroncalRemoto" => Next the error I've shown on my PS.

We haven't tested on the Huawei cloud platform but if your network settings are correct then that wouldn't be the cause of this issue.
Can you start dsiprouter in debug mode and attach the stack trace from /var/log/dsiprouter.log?

You can start in debug mode by running:

dsiprouter restart -debug

@OsvaldoSierra please attach dsiprouter.log from when this issue occurs

[OsvaldoSierra]

Hi team! Sure, I'll share it with you in a few hours

dsiprouter.log

Hi team. Here I'm adding the dsiprouter.log. I've replied the error after dsiprouter restart -debug command. The testing time was at:

Issue occurs due to no weight validation in endpoint group api checks.
This should not happen in normal use as the api puts in a default value.

Below is a workaround that will allow the attrs column of the dispatcher table to be empty:

diff --git a/gui/modules/api/api_routes.py b/gui/modules/api/api_routes.py

-                for item in dispatcher:

             for endpoint in endpoints:
                 ep = {}

Will commit a better solution in v0.72, the workaround is only temporary
