Signal API bug with persistent storage

[schklom]

📣 Notification Service(s) Impacted
Signal-api

🐞 Describe the bug
Signal API works with Apprise's CLI (although with a warning), but fails with the Web-UI and the Web API.

💡 Screenshots and Logs

command to trigger this with the stateful API

$ curl -X POST -d '{"tag":"signal", "body":"test message"}' -H "Content-Type: application/json" https://apprise:12345/notify/apprise
{"error": "One or more notification could not be sent."}

and the Apprise configuration file

urls:
  - signal://signal-api:8080/123456789:
    - tag: signal

The CLI works but triggers a warning

$ docker exec -it apprise bash
$ apprise -vvv -t "Test Message Title" -b "Test Message Body" \
   signal://signal-api:8080/123456789

2022-08-24 22:34:57,640 - DEBUG - Socket Exception: HTTPConnectionPool(host='signal-api', port=8080): Read timed out. (read timeout=4.0)

and the stateless API works for some reason despite the message

$ curl -X POST -d '{"urls":"signal://signal-api:8080/123456789", "body":"test message"}' -H "Content-Type: application/json" https://apprise:12345/notify
One or more notification could not be sent.

In short:

• stateless Web-API works
• stateful (persistent storage) Web-API fails
• CLI works
• Web-UI notification test fails

My guess is that Apprise does not translate the configuration into a proper call.

💻 Your System Details:

• OS: Debian 11
• Python Version: 3.10.6

🔮 Additional context
I am using the latest Docker image (v0.8.0).

Interesting, is your curl command taking longer then 4 seconds? The error implies your timing out.

What happens if you do:

# Increase the connection timeout to 30 seconds
apprise -vvv -t "Test Message Title" -b "Test Message Body" \
   signal://signal-api:8080/123456789?cto=30

[schklom]

Setting cto=30 does nothing for some reason

however, setting rto=30 does not produce a warning

2022-09-01 14:58:59,697 - INFO - Sent 1 Signal API notification to 123456789.

Is there a way to set rto=30 in the YAML configuration?

[caronc]

You should be able to just add it and it will work:

...
urls:
   - signal://credentials?rto=30
      - tag: signal

Or this should work too:

...
urls:
   - "signal://credentials":
      - tag: signal
        rto: 30

Surprised to see it take as long it does. One thing i could do is just bump the default value of the read timeout for signal in Apprise from 4 seconds to... 10? I mean it seems a little strange it's taking longer then even 4 seconds to communicate with your server. Is your machine under a lot of stress? Or is it an older one that has these delays from time to time?

What happens if you do:

time apprise -vvv -t "Test Message Title" -b "Test Message Body"    signal://signal-api:8080/123456789?rto=30

I'd be curious the time it is taking (do it a few times maybe so you can get like an average

[schklom]

It seems to take about 12 seconds for me on average (repeated 5 times). I have about 30 running Docker containers, but the machine is rarely under any load.

real    0m12.545s
user    0m2.560s
sys     0m0.246s

But this is a fairly minor problem, the main issue is that I cannot trigger signal remotely using a configuration (stateful).

Unfortunately, adding rto: 30 to the YAML configuration does not solve it: both Web-UI and stateful curl triggers fail.

YAML

urls:
  - "signal://signal-api:8080/123456789":
    - to: 123456789
      tag: signal
      rto: 30

leads to the Web-UI log

and the Docker Apprise log

curl with the stateful configuration leads to the same Docker Apprise log.

I hear you. Looks like this is definitely a bug. I'll investigate further and let you know as I learn more or can patch it up 👍

This has been fixed now in the master branch. 🚀 Closing this ticket off
