type photo: EFATAL: TypeError [ERR_INVALID_CHAR]

[OKDaG]

Hi, i'm running nodered v2.0.6 with node-red-contrib-telegrambot v10.0.7 and wanted to send a photo with Telegram Sender but got this error:

msg.payload: object {"chatId":279600xxx,"type":"photo","content":"/tmp/cam.jpg","caption":"Hof"}

msg.string[349] Caught exception in sender node: Error: EFATAL: TypeError [ERR_INVALID_CHAR]: Invalid character in header content ["getKeyByValue"] when processing message: {"_msgid":"e06280de37aaa560","payload":{"chatId":279600xxx,"type":"photo","content":"/tmp/cam.jpg","caption":"Hof","options":{"caption":"Hof","chat_id":279600xxx,"photo":null}},"topic":""}

Any hints?

[windkh]

Thanks for reporting. I have never seen this before. Is it reproducable? Can you send me the flow with an example photo via email?

this loads an external jpg from wikimedia, result is the same error without sending the image

[windkh]

I just tried your flow. It works here. Well I had to change the path to "c:/temp/test.jpg" because I am running under windows. So basically the image is ok and the flow, too. The only thing left is the file on the harddisc. Can you directly send the image without accessing the harddisc by just assigning the image buffer to content as follows content: msg.payload,

see also https://discourse.nodered.org/t/taking-a-picture-and-sending-it-via-telegram/27905/4

[OKDaG]

That's strange, i also tried it without storing the image on the harddisc, same error. nodered ist running here as a docker container, fresh installation on two different systems (both hosts ubuntu 20.04 with docker 20.10.7 running nodered/node-red:latest@sha256:ddd05759e91dce9db82d36a3df66011936cc49d59ac329589df379c44e74867e).

and that's also weird, tried it on raspi without docker and it works.

[windkh]

Ah ok. So if you run inside docker you get the error in the sender node. Maybe we can get the callstack either via the console of node-red or maybe in the second output see

After reinstalling nodered and just install node-red-contrib-telegrambot the error is gone. Guess this is related to some other plugin. Will report which one if i found it.

[windkh]

Good news… yes please keep me informed

[Speeedy0815]

Hi Guys,

I get the same error. Maybe you can help me. I'm running on RaspberryPi, no Docker.

Tryed to read first and forward the buffer. And I tryed also with filepath --> same error.

"Caught exception in sender node: Error: EFATAL: TypeError [ERR_INVALID_CHAR]: Invalid character in header content ["getKeyByValue"] when processing message: "

I can not reinstall everything, because of running system here.

Can you help me?

Thank you.

[windkh]

@Speeedy0815 can you send me the image and the flow?

[Speeedy0815]

Hi @windkh,

I sent you both via mail.

Thank you for your fast answer.

[windkh]

Hi, I had a look at your flow and found two things:

1. If you use \ you have to escape it with a second \ in front of it: so always use \ when passing a path.
2. Always use ' when passing a string property. Not anything like ´ or . In your flow the message was written like message:asde`,

Example that works for me

var payload = {
  content: 'C:\\Temp\\test.jpg',
  message:  'asde',
  type : 'photo',
  chatId: 12345678,
}

msg.payload = payload;
return msg;

[Speeedy0815]

Hello @windkh,

Doesn't work.

1. I have Linux paths with '/'. I don't have to escape them. (I tryed --> File not found)
2. I changed the wrong "`", but it doesn't help. Same error.

Is it possible to get some more information? Can I debug something?

[windkh]

You can try this and send me the output. Please send me the image that you want to send via private email.

[Speeedy0815]

1. using path:

   {"_msgid":"bfaa219966764eba","payload":{"content":"/home/pi/bilder/g_s.jpg","message":"asde","type":"photo","chatId":120437710,"options":{"chat_id":120437710,"photo":null}},"error":"Caught exception in sender node:\r\nError: EFATAL: TypeError [ERR_INVALID_CHAR]: Invalid character in header content [\"getKeyByValue\"]\r\nwhen processing message: \r\n{\"_msgid\":\"bfaa219966764eba\",\"payload\":{\"content\":\"/home/pi/bilder/g_s.jpg\",\"message\":\"asde\",\"type\":\"photo\",\"chatId\":120437710,\"options\":{\"chat_id\":120437710,\"photo\":null}}}"}

2. using buffer

I took the buffer and tried to send it:

However it seems that the image is not complete. So again: can you send me the picture as jpeg to my private email?

[windkh]

is this still an issue or can I close it? @Speeedy0815

[Speeedy0815]

Hi @windkh,

I tryed it in Oktober after your mails. But it didn't work.

But I can't try it anymore because I haven't installed node-red-contrib-telegrambot anymore.

I use now node-red-contrib-telegrambot-home. (But here i can also not send photos)

I don't know what is wrong here. By the way --> sending via mail is working.....

So, thank you. You can close it.
