Power Automate grabbing attachments from email account and placing them in a local drive errors

Posted on by sdrakedrake

Hopefully this is an easy one for you guys. But the flow is to monitor emails in the inbox folder.
Whenever a new email comes through, if it has an attachment, it will take that attachment and place it in a folder on a local shared drive under a specific naming convention.

Where I'm getting stuck at is how to do the condition aka check if the email has an attachment or not.

Trigger is When a new email arrives in a shared mailbox (V2). Parameters in the trigger is "Include attachments" = yes and "Folder" = inbox.
The condition is what I have so far:

length(triggerOutputs()?['body/Attachments']) greater than 0.

I get the error below. Not sure what else to do here.

Ok think im getting closer:

New screenshot shows that errors are gone. However its skipping the "apply to each part."
ActionBranchingConditionNotSatisfied
The execution of template action 'Apply_to_each' skipped: the branching condition for this action is not satisfied.

I initialized the variable as an array.
And condition is still:

length(variables('EmailAttachments')) is greater than 0..

Apply to each is the email attachments from the variable.

Hi

Sorry I am not following.

What is the Input to the Apply to Each. It cannot be a Number, so its not the length of anything.

Please do in and open the Apply to each. Look a the inputs and outputs it will explain why it didn't do anything.

But what I would like to see specifically is the actual Expression you put in the Input for the Ate.

Thanks,

Currently there isn't an input for the apply to each. Below is the screenshot. It only says "Select an output from previous step" for the parameter.

Let me try and type it out as it might be easier to follow:
Step 1: Trigger - When a new email arrives in a shared mailbox (V2)

Parameters: Include attachments_Yes

Folders_Inbox

Step 2: Initialize Variable - Name: EmailAttachments

Type: Array

Value: Blank

Step 3: Compose - Inputs: EmailAttachments (from initialize variable)

Step 4: Condition - Condition expression

length(variables('EmailAttachments'))
is greater than
0

Step 5: True - Apply to Each - EmailAttachments (from initialize variable)

Step 6: Compose (where im trying to do the naming convention)

Step 7: Create file

Step8: Move Email

Ok im going to make this a lot less complicated.
New flow is as follows:

Trigger - When a new email arrives in a shared mailbox (V2)
Parameters - Only With Attachments and Include Attachments = Yes

Step 2 - Apply To Each
Parameters - Select an output from previous steps* - Attachments

Step 3 - Create a file (File System SINCE its on a share Drive)

The current error is
Action 'Create_file' failed: Key 'gateway' not found in connection profile.

So im assuming this error is being caused by some connection issue. Googling trying to figure this out, but point is, I think I have the Condition error resolved. This new error is from the File System action.
