Node Red - Telegram - Multiple Line Message

Hi,

Struggling to send multiple line messages using notify.telegram via node red. Seems “\n” which works fine when sending notifications via email doesnt work with telegram. Any ideas?

I have for example this function node:

Calling this service node:

But throws this error:

Call-service API error. Error Message: extra keys not allowed @ data[‘0’]

Had same error with call service. Please find solutions here
