Manually triggered flow fails with no authentication headers

[PeterVincent]

I want to have a single flow that get's called from lots of libraries rather than recreating the same flow on each library using the For the Selected File trigger.

I have a simple flow that is triggered manually.

There is only one action which is to get file properties.

When the flow is called from a library (column formatted button) it has the itemID, siteURL and itemURL. This is enough to use the Get File Properties action. However this action fails with an error message saying:

The template language expression 'json(decodeBase64(triggerOutputs().headers['X-MS-APIM-Tokens']))['$connections']['shared_sharepointonline_1']['connectionId']' cannot be evaluated because property 'X-MS-APIM-Tokens' doesn't exist

When the flow is triggered from within the Flow service the get file properties action works (if i hard code what file to get).

The header's do contain the X-MS-APIM-Tokens attribute.

What is the point of manual triggered flows if they are given context information but no authentication info?!

Hi @PeterVincent ,

Could you please share a screenshot of the configuration of the flow?

Hi @PeterVincent ,

Please choose the Library Name from the drop-down list.

The drop down list does not have Site Pages.

I have a second flow that is currently moving pages into sub-folders in the Site Pages library of another site collection.

I am assuming that if manually entering the name of the library works for the Move File action then it would also work for the Get File Properties action.

I am testing this on a communications site collection, for background information.

Hi @PeterVincent ,

Does your issue still exists?

Yes it does. There have been no other suggestions so nothing has changed.

I have tried with other libraries in other site collections but the same error happens.

Does Microsoft know that this is a reproducible bug in Flow?

Any help with solving this would be greatly appreciated.
