Hi @redg1402 ,
Have you managed to resolve this?
It looks like you have tried a few different variations, and have come up against a few different error messages. The error “Error: no_text (200)” may just indicate that the Blocks were not recognized.
I can see from your screenshot that you have right-clicked on the Slack module and selected “Run Once”. This will only run the Slack module, so there would be no values populated in your structure (because the CMS has not been involved), so it sounds like when you received the “structure but without any values”, that was a successful test!
If you set the module up in the same was as you did when you got the “structure but without any values”, then try running the whole scenario, so that it picks data from the CMS and then populates your Slack module, you may find it comes out as expected.
