[Error] Bad Request: can't parse entities

[euphoria360]

:beetle: Describe the bug I am using Apprise API Docker on my home server to send messages to my Telegram Group. A script on another system sends messages to it using curl post command. Everything was working fine until around April 17th when messages stopped coming. Today I started looking at the script and saw that Apprise complains about characters in the message. the message is:

*Home-S [Sonarr]:* Test
Testing if Sonnar can Send us any Massage.
If you got this, then Hurrayyyyy!!!

It is being sent to Apprise via this command: printf "$message\n" | curl -X POST -F "body=$(</dev/stdin)" "$appriseurl"

And this is the error:

2024-05-07 12:04:36,241 [INFO] apprise: Loaded 1 entries from memory://
2024-05-07 12:04:37,340 [WARNING] apprise: Failed to send Telegram notification to -1001234567890: Bad Request: can't parse entities: Character '-' is reserved and must be escaped with the preceding '\', error=400.

I tried to send a simple message via curl and again same happened:

curl -X POST -F "body=home-s" "http://192.168.48.6:8008/notify/tg-nasbot"

2024-05-07 12:15:01,689 [INFO] apprise: Loaded 1 entries from memory://

If I remove '-', other characters like []: will get complains too. this was not the case before. what should I do?

:computer: Your System Details:

• OS: Apprise API Docker container

Update: I finally fixed it by piping my message through sed and escaping all special characters. So far it works: printf "$message\n" | sed "s|[-.\!()%&#?/@+':]|\\\&|g" | curl -X POST -F "body=$(</dev/stdin)" "$appriseurl"

Are you passing in a - on the URL?

[euphoria360]

yes. for example, in this command curl -X POST -F "body=home-s" "http://192.168.48.6:8008/notify/tg-nasbot" the - is passed as part of home-s word

If I escape the - as Apprise says, like curl -X POST -F "body=home\-s" "http://192.168.48.6:8008/notify/tg-nasbot" the command runs successfully. But the problem is that the messages sent by the script are dynamic and I don't know the content beforehand. Also, I don't know what characters Apprise doesn't like.

I can't reproduce this at all

curl -X POST -F "body=home-s" -F tag=telegram "http://localhost:8000/notify/chris"
2024-05-13 19:08:42,013 [INFO] apprise: Loaded 3 entries from memory://
2024-05-13 19:08:42,515 [INFO] apprise: Sent Telegram notification.

In the above example, i map the telegram tag so that i only send a notificatoin there, but even if i drop the tags, the dash in the body has no problem (and does not need to be escaped at all.

Also, I don't know what characters Apprise doesn't like.

To ansewr this, there is nothing it doesn't like :wink: . It just passes things along . There is something else happening in your case. I'm in an Linux environment for my test, are you in the same ?

Instead of using curl... just as a test, try installing hte local apprise tool and see if you can get more details out of the logs:

pip install apprise

# -vvvv is a very, very verbose output
# you can possibly test your command you were doing too;
# if no -b (--body) is specified, then stdin is used by default, so the below should work fine:
printf "$message\n" | sed "s|[-.\!()%&#?/@+':]|\\\&|g" | apprise -vvvv "$appriseurl"
