Error in HTTP POST requests - RESTfulAPI

[shreyask92 (Shreyas Krishnamurthy)]

Hi,

I am trying to connect my bot with a chat interface on a website using REST API. Before doing so I started testing the available web server routes. All the GET requests work prefectly fine, but I am getting errors when I try executing POST requests.

Additional Info - I have the bot running on a remote docker container. I used the image rasa/rasa:latest-spacy-en

$curl http://<server-ip>:<port>/webhooks/rest
{"status":"ok"}

$curl http://<server-ip>:<port>/
Hello from Rasa: 1.1.4

$curl http://<server-ip>:<port>/webhooks/rest/webhook -d '{"sender":"default","message":"Hello"}'
Error: Failed when parsing body as json

$curl http://<server-ip>:<port>/model/parse -d '{"text":"Hello"}'
{"version":"1.1.4","status":"failure","message":"An unexpected error occurred. Error: Failed when parsing body as json","reason":"ParsingError","details":{},"help":null,"code":500}

And I found this in the container logs

## Server side error message
During handling of the above exception, another exception occurred:

    raise InvalidUsage("Failed when parsing body as json")
sanic.exceptions.InvalidUsage: Failed when parsing body as json

Any suggestion on what I would be wrong? or am I missing any configurations?

Hey @shreyask92, you can refer this post

Rest api implementation

Hey @chinnusujitha, just follow the below steps to connect your bot to custom channel using REST api, Step1: you need to ensure your credentials.yml has the following content: [image] Step2: Once you have trained your bot, you can start your bot server by running the below command rasa run -m models --enable-api --cors “*” --debug Once you run this command, you can see the below output in the terminal [image] Step3: Once your server is up and running you can access your bot throught RE…

Hope this helps you

@shreyask92 i am facing this same error , did you find a solution ?

[shreyask92 (Shreyas Krishnamurthy)]

Hi @saida

Yes I did. I was using “rasa run -vv --enable-api”. I changed this to “rasa run -m models --enable-api --cors ‘*’ --debug” and it started working.

Give it a try and let me know if its not working.

Continuing the discussion from Error in HTTP POST requests - RESTfulAPI:

Hi ,

I have followed all the steps to run the rasa model provided in this link https://towardsdatascience.com/a-beginners-guide-to-rasa-nlu-for-intent-classification-and-named-entity-recognition-a4f0f76b2a96

But I am unable to fetch the intents and entities while running the CURL . Error: {“version”:“1.1.5”,“status”:“failure”,“message”:“An unexpected error occurred. Error: Failed when parsing body as json”,“reason”:“ParsingError”,“details”:{},“help”:null,“code”:500}

Can somebody help me to solve this issue ?

@sravya I am also facing the same issue. Were you able to resolve this?

[shreyask92 (Shreyas Krishnamurthy)]

@aayush3011 Try the solution in post#4. If that step was fine then, just try the below code (change the url as required)

curl localhost:5005/model/parse -d "{\"text\":\"hello\"}"

The problem is with how the body is sent. Just use the backslash to escape the " characters and it will start working.

Hi I am also facing this issue

Buttons are not working. Please help with proper steps and do I have to add any url in interactivity sections of App ?

[JiteshGaikwad]

hey @dharvi, you can check this thread:

Slack integration error with interactive components

hey @cck197, check this issue in this I have mentioned the workaround that I did to overcome this issue: I am not pretty sure whether this is a reliable solution

[KhalidBentaleb]

Hey @JiteshGaikwad I’m receiving Slack messages using Python flask and I want display them in a chatbot UI

[JiteshGaikwad]

Which UI are you using and what messages do you want to show?

[KhalidBentaleb]

I’m using your UI and I want messages from slack channel

[JiteshGaikwad]

Ok. So do you want to send the bot messages from slack or something else?

[KhalidBentaleb]

I want to replace rasa with human agent, so I create custom actions to send message to slack channel and I’m using flask for receive messages

[JiteshGaikwad]

I think so we have discussed this in some other post, I haven’t worked yet on slack human agent-handoff yet but will soon do it.

@KhalidBentaleb

I want display them in a chatbot UI

Actually this UI was designed to handle bot response from Rasa but if you want to do something else you need to modify the UI script to handle those responses.

[KhalidBentaleb]

okeey, I’ll try

Thank you @JiteshGaikwad
