The problem

I can’t seem to edit a flow to add a step to it. The browser console emits an error:

main.bd08e7b5ad2ce0b417ba.js:1 TypeError: Cannot read property 'action' of undefined
    at n.ngOnChanges (11.bb2047dff352bcbffb47.js:1)

    at il (main.bd08e7b5ad2ce0b417ba.js:1)

Expected behavior

I should be able to edit and add steps as needed to the flow.

API Endpoints and Schemas

I only see GET requests to /api/v1/integrations/i-LNUix7uR6BhTm3sXS83z and /api/v1/monitoring/integrations/i-LNUix7uR6BhTm3sXS83z, probably unrelated.

Tasks involved / Steps to Reproduce

1. Create API provider based integration
2. Try to edit one of the flows to add a step

I believe the set-body extension currently don’t work if you compile with 1.5-SNAPSHOT syndesis dependencies.
