Connection references - child flows tested individually fail when run in main flow

Hi!

I have a solution with a very simple main flow and 3 child flows triggered inside (namely, the main flow contains only 4 objects: one powerapps trigger and 3x run child). All flows have connection references everywhere (I use 1x sharepoint, 1x excel and 1x outlook connection references defined in the solution). The 3 child flows pass the tests successfully when tested individually, but when I trigger them from the main flow I get this:

"Failed to parse invoker connections from trigger 'manual' outputs. Exception: Could not find property 'headers.X-MS-APIM-Tokens' in the trigger outputs. Workflow has connection references '["shared_sharepointonline_1"]' with invoker runtime source."

What is also surprising is that it sometimes happens and sometimes it works on the same setup. Now I have no clue, why is that. Any ideas how to fix this?

Are you using the Flow's Test button or invoking the flow manually?

If you are using the Test option, it won't work on new connections added since the last time the test was run.

Try invoking the flow manually or via the appropriate trigger.

Hi!

@SudeepGhatakNZ thanks, but that was not it - I run them both ways before posting the issue.

I did a lot of things in order to try and make my flows work again. I succeeded eventually. The most probable fix was that I went through all the connection references and discovered that on a single sharepoint step I edited in the flow, there was a "run only user" connection that messed up everything around it. What I do not know is how on earth I got "run only user" on a step, that was connected with the valid connection reference before the editing. Is it possible that if you open the flow to edit from the "my flows" section instead od of the "solutions" section it breaks the connections on the steps that were changed? This is the only cause I can think of now.
