I'm trying out your Salesforce webhook creator in a sandbox. I was able to create the webhook but I can't view them under the Saved Webhooks tab. When I use Firefox an error modal appears:
A Component Error has occurred!
Message: TypeError: Error in $A.getCallback() [result[i].Body.split(...) is undefined]
Callback failed: apex://Krysp.WebhookAllLogs/ACTION$getAllTrigger
Stack Trace: myAction/<()@https://xxxxxxxx.sandbox.lightning.force.com/lightning/n/components/Krysp/WebhookAllLogs.js:14:46
When I use Edge I don't get any errors, either on the screen or in the browser console, however none of my webhooks are displayed, it's just an empty table.
