Flow fails on new item: multiple content types, one missing referenced column

[Mart1]

Hi,

Background

My flow runs on a new item in a SP list and builds a new item in a separate list.

The triggering list has four content types:

• A (columns 1, 2, 3, 4)
• B (columns 1, 2, 3, 4)
• C (columns 1, 2, 3)

The new item is built from columns 1, 2, 3, 4. It has a condition so it only creates the item item for content types A, B, so the flow is safe to run for content type C.

Problem

When I add items of content type C, the flow fails as follows:

The API 'sharepointonline' returned an invalid response for workflow operation 'When_new_SHE_Report_is_created' of type 'OpenApiConnection'. Error details: 'The API operation 'GetOnNewItems' is missing required property 'body/value/0/Brief_x0020_Description_x0020_of'.'

Current assessment and attempted remedy

The failure seems to be because the triggering content type is missing referenced column 4 (even though logic means it will never actually hit that reference). I tried adding 'content type is A or B' logic to the trigger conditions, but that didn't help.

Any suggestions welcome, I'm currently out of ideas.

Many thanks,

I found a solution:

1. Removed direct references ('dynamic content') to the sometimes-missing column name.

2. Replaced with a Concat expression taking the column name and '' as follows:

• concat(triggerOutputs()?['body/Brief_x0020_Description_x0020_of'],'')

I hope this helps somebody.
