Unable to parse JSON from HTTP request

Posted on by GTMRA

Hello,

using a HTTP request that returns a simple JSON string. Regardless of how I tried to return the JSON i am always getting the following message :

Error Message: The provided value for path ‘Topic.Var1’ cannot be parsed into ‘RecordDataType’ type. Provided value: “{”“msg”“:”“Welcome, how can i help you ?”“,”“name”“:”“”“,”“timestamp”“:1700574123}” Error Code: ValueParsingError Conversation Id: 0b50d6ad-54f9-4884-9823-04a737136450 Time (UTC): 2023-11-21T13:42:03.078Z

For simplicity, The JSON response does not require any headers and/or body data to be returned, it is always returned on every request.

This is the JSON string :

{"msg":"Welcome, how can i help you ?","name":"alexggg","timestamp":1700574256}

What do I need to adjust in order to make this work ?

Thank you for your help.

Re: Unable to parse JSON from HTTP request

Thank you for your help. The headers were incorrect and needed to be set to :

Content-Type: application/json; charset=utf8

Re: Unable to parse JSON from HTTP request

Thanks @GTMRA

I think you get this error because your API returns your JSON as text/html; charset=utf-8 and not as JSON (I was initially puzzled in Postman as it wouldn't format the content nicely).

To work around this, you can switch to the code editor view and update your HTTP request node to set the responseSchema to Any

You can then parse it with the desired schema in a subsequent Parse value node:

And it now works:

Re: Unable to parse JSON from HTTP request

I can't repro, I guess because I don't have access to the API.
Error Message: HTTP request failed with status code 403 Forbidden. Error Code: HttpRequestFailure Conversation Id: ba2ff1c9-382c-4939-ac82-91bb35f20b8b Time (UTC): 2023-11-21T14:36:37.860Z

Are you use the API returns a clean JSON? What does the GET request look like when you open https://chatapp.azurewebsites.net/chat.php in your browser or in Postman?

Re: Unable to parse JSON from HTTP request

Can you paste it here or send it as attachment, perhaps over private message?

Can you share the schema?
Or the full topic YAML?

Re: Unable to parse JSON from HTTP request

Did you edit the schema?

You can do that easily by selecting "From sample data" in "Response data type" :
Pasting the JSON here:
Will generate the following schema:
