SyntaxError: Unexpected token < in JSON at position 0 - Webhook Integration (ITOMIG GmbH) v 21.1.0, iTop 3.0.00-beta5-8216

[Michael Newman]

Hey all,

I'm working on setting up Slack integration with iTop 3.0.0-beta5 using v21.1.0 of the Webhook Integration found here. I appear to have successfully installed the extension (put in Extensions folder, reinstalled iTop, have the appropriate php modules set up, restarted Apache). I have created a trigger on public log update that should both send an email to caller and send a Slack notification to a channel in my Slack workspace.

When I post a public log update, however, Chrome gives me an error "SyntaxError: Unexpected token < in JSON at position 0" and the Slack message does not send. The email trigger works fine.

I'm at a loss. Based on searches, I suspect maybe I've got issues with cURL, but I have activated cURL and have successfully run a script that suggests it is appropriately installed.

Any thoughts? Details of everything below:

Server OS: Windows 10
Apache version: 2.4
PHP version: 7
iTop version: 3.0.0-beta5-8216
Webhook Integration version: 21.1.0
Chrome version: 94.0.4606.71 (Official Build) (64-bit)

Can you debug and see what input you do receive? Probably non JSON format, but still some form of response?

I'm not too technically inclined, so please feel free to let me know if you need something more specific:

When I click "Send" on the ticket, I get the error and this is what I have in

Hello,

Unfortunately I can't answer on this as this extension was done by Itomig and not by Combodo.
Note that Itomig is a Combodo partner though ; and I can assure they do a fantastic job with iTop and its ecosystem !

Note also that final 3.0.0 (both products and community) will include a webhooks integration done by Combodo, including a Slack integration for notifications. For now this module is in its own repository but in the end it will be included in iTop repo.
The development is in its final stages now !
