There was an error rendering this rich post.

Hi, I have built a Domo Custom App to call an AWS Lambda Function with domo.post.

There's no problem in managing the response when all goes fine.

But I haven't found how to extract the ErrorMessage from the response when it gives an error (HTTP errorcode: 400)

Can someone tell me where domo keep this information?

Thanks

@StefanoG who is sending the 400 error? Domo or AWS?

are you saying you're unable to capture the response from domo.post? b/c it seems to me you would just async / await and console.log the response.

StefanoG

Hi Jaew,

the 400 error came from AWS.

Iif use as client PostMan or the Python requests lib i got 400 as status_code

and the ErrorMessage, a specific message for every cause :

{

"ErrorMessage": .........

}

Why Domo.js don't throw the message but give me an generic "network error"

I wish detect if is a 429 or a 408 or is an application error because the request parameters are no corrects

... i didn't write domo.js :P

why don't you just send curl requests?

StefanoG

Inside the Domo CustomApp I use domo.post to make REST Get and Post,

I don't even know if I can use curl in an the CustomApp JS script

@Stefano true. send a fetch or any other async method of querying APIs in JS.

StefanoG

OK, thanks, as study case i will try to use curl, but i think that this insn't be the best solution to make REST call.

I hope that in a next version domo.js add a better handling of HTTP errors and return to the caller the status_code and the errormessage that it catchs

I get a the message.

@StefanoG in your devtools network request can you see more information? Can you see the actual error message?

When I do a domo request the promise rejects and I get the error message:

StefanoG

Hi n8isjack,

Is in the devtools network i see the errormessage

But in the console i see

where the code of app.js for the request is:

let aws_cf_url = `${CONFIG_DATA.AwsLambdaURL}`
const options = {contentType: "application/json"}
domo.post(aws_cf_url, req_body, options).then((ext_result) => {
  console.debug("ext_result: " + JSON.stringify(ext_result))
 ...
 ...
 ...
}).catch((error) => {
console.error("->" + error.toString())
})

The error var is empty!!!
There is a way to access at errormessage in the app.js code?

Thanks
