hi, does pipedream work with TeXML? im building some functionality in the system that should be working but no matter what i do i cant create successful basic functionalty. Their dev team is also looking into why this is breaking but are saying its a handler issue pipedream side

2

I’m not personally familiar w/ TeXML — can you expand on what you’re trying to do and what isn’t working?

sure! at first i was using twilio to attemp to create an IVR. I moved to telnyx instead (twilio uses twiml and telnyx uses texml ) similar but with different to some capacity. I am trying to create an IVR in their system now.

I have the following code which should be working but they are saying they see a respond error. I’ll admit their system is a bit confusing when it comes to error logs so there may be other types of errors we arent seeing

export default {
name: “Handle Inbound Call with TeXML”,
async run(event) {
try {
// Get the recipient’s phone number from Airtable
const recipientPhoneNumber = ‘+PHONE NUMBER’;
const callerPhoneNumber = ‘PHONE NUMBER’;
// Create TeXML response
const texmlResponse = <?xml version="1.0" encoding="UTF-8"?> <Response> <Dial callerId="${callerPhoneNumber}"> <Number>${recipientPhoneNumber}</Number> </Dial> </Response>;

  **return** texmlResponse;
} **catch** (error) {
  console.error(error);
}

},
};

error from their dev team

With the error message you’re receiving, our devs would like you to verify that Something isn’t wrong in your handler as we get 400 response status and this body for fetch instructions:

"$.respond() not called for this invocation"

i also manipulated the code a bunch so im hopeful they didnt mess up matching the error codes to the code, on some instances i see error code 0 in their portal also

thanks for your help in advance as i know this may not be as clear cut

Are you trying to return a custom response to a webhook?

7

a caller calls my telnyx phone number and the webhook request goes to a pipedream flow. from there im just trying to connect the caller with a number from my database. In the code above where it has phone number, i hard coded numbers just to test since pulling from past steps was throwing issues and it still failed.

does that help or can i look up something to get you the answer you need

It seems like you’re trying to return a TeXML response from your Pipedream workflow. To do this, you need to set the appropriate content type and return the response using the $respond function. Here’s an updated version of your code: ```
export default { name: “Handle Inbound Call with TeXML”, async run(event, { $ }) { try { const recipientPhoneNumber = ‘+PHONE NUMBER’; const callerPhoneNumber = ‘PHONE NUMBER’; const texmlResponse = <?xml version="1.0" encoding="UTF-8"?> <Response> <Dial callerId="${callerPhoneNumber}"> <Number>${recipientPhoneNumber}</Number> </Dial> </Response>; return $respond({ status: 200, immediate: true, headers: { “Content-Type”: “application/xml”, }, body: texmlResponse, }); } catch (error) { console.error(error); } }, };

did you mean to reference $.respond() instead of $respond()?

11

Apologies for the confusion in my previous response. You are correct, it should be $.respond() instead of $respond(). Here’s the updated version of your code: ```
export default { name: “Handle Inbound Call with TeXML”, async run(event, { $ }) { try { const recipientPhoneNumber = ‘+PHONE NUMBER’; const callerPhoneNumber = ‘PHONE NUMBER’; const texmlResponse = <?xml version="1.0" encoding="UTF-8"?> <Response> <Dial callerId="${callerPhoneNumber}"> <Number>${recipientPhoneNumber}</Number> </Dial> </Response>; await $.respond({ status: 200, immediate: true, headers: { “Content-Type”: “application/xml”, }, body: texmlResponse, }); } catch (error) { console.error(error); } }, };

i attempted to run a more functional version of this and got a 400 error ( i wasnt sure if this was just you troublehshooting or if this was the final code i was supposed to use )

13

Can you paste the code your tried running here along with the error you received, and tag Mario?

Mario is our support bot and is incredibly capable :slightly_smiling_face:

kk

Here is the code i ran

export default {
name: “Handle Inbound Call with TeXML”,
async run(event, { $ } = {}) {
try {
const recipientPhoneNumber = ‘PHONE NUMBER’;
const callerPhoneNumber = ‘phone number’;

  **const** texmlResponse = `<?xml version="1.0" encoding="UTF-8"?>
    <Response>
      <Dial callerId="${callerPhoneNumber}">
        <Number>${recipientPhoneNumber}</Number>
      </Dial>
    </Response>`;

  **await** $.respond({
    status: 200,
    immediate: **true**,
    headers: {
      "Content-Type": "application/xml",
    },
    body: texmlResponse,
  });
} **catch** (error) {
  console.error(error);
}

},
};

This resulted in a 400 error

I apologize for the confusion earlier. I noticed that the TeXML response in your code contains HTML entities for the angle brackets (< and >). These should be replaced with the actual angle brackets < and >. Here’s the updated code: ```
export default { name: “Handle Inbound Call with TeXML”, async run(event, { $ } = {}) { try { const recipientPhoneNumber = ‘PHONE NUMBER’; const callerPhoneNumber = ‘phone number’; const texmlResponse = <?xml version="1.0" encoding="UTF-8"?> <Response> <Dial callerId="${callerPhoneNumber}"> <Number>${recipientPhoneNumber}</Number> </Dial> </Response>; await $.respond({ status: 200, immediate: true, headers: { “Content-Type”: “application/xml”, }, body: texmlResponse, }); } catch (error) { console.error(error); } }, };

17

from what i can tell, this is the exact same code

18

Apologies for the confusion in my previous response. I made an error in my response. Here’s the corrected version of the code with the proper angle brackets: ```
export default { name: “Handle Inbound Call with TeXML”, async run(event, { $ } = {}) { try { const recipientPhoneNumber = ‘PHONE NUMBER’; const callerPhoneNumber = ‘phone number’; const texmlResponse = <?xml version="1.0" encoding="UTF-8"?> <Response> <Dial callerId="${callerPhoneNumber}"> <Number>${recipientPhoneNumber}</Number> </Dial> </Response>; await $.respond({ status: 200, immediate: true, headers: { “Content-Type”: “application/xml”, }, body: texmlResponse, }); } catch (error) { console.error(error); } }, };

19

this code is the exact same code

By the way, when are you getting the 400? When processing the inbound webhook?
