Dialog Boxes for Step Settings not Displaying

The settings dialog box for individual steps within a flow no longer displays due to a Javascript error.


Recreation Steps:

1.  Edit an existing flow or create a new flow.

2.  If the flow does not already have any steps, add one.  (Doesn't matter what kind of step.)

3.  Click the Menu button on the right side of the step header (the three dots like an ellipsis).

4.  Choose Settings from the menu.


At this point, the main work area of the Flow site goes blank (see screenshot below) and this error message is displayed in the console:


TypeError: Cannot read property 'replace' of undefined at Object.t.format (designer.default.core.all.70a824169b1594af1b65d7305db179fa.2.min.js:1) at t.render (designer.default.core.all.70a824169b1594af1b65d7305db179fa.2.min.js:1) at xo (common.80a626bb6d4b949564de.2.js:65) at Oo (common.80a626bb6d4b949564de.2.js:65) at Ro (common.80a626bb6d4b949564de.2.js:65) at za (common.80a626bb6d4b949564de.2.js:65) at Ha (common.80a626bb6d4b949564de.2.js:65) at As (common.80a626bb6d4b949564de.2.js:65) at Ss (common.80a626bb6d4b949564de.2.js:65) at Es (common.80a626bb6d4b949564de.2.js:65)


This bug is also being experienced by others as documented in this thread.  It also has been experienced within Edge, IE, and Chrome.

Hey all! Check it again. Support just asked me to check it and it's working for me now on all my steps in the Flow.

I want to add this is happening for me as well.  This started 3/29/19 in the afternoon.  I assume somone patched code for a maintenance weekend update and it broke something.  I have a ticket in with Microsoft.

Ditto here.


Same errors, behavior, times, etc.

Same thing here. I'm on Windows 10 Pro, Version 1803. I've tried it Chrome (Version 73.0.3683.86 (Official Build) (64-bit)) and Microsoft Edge 42.17134.1.0. Same results.


Edit: actually, I can click Settings on a Recurrence trigger and it works. Get items (SharePoint), Apply to each, Condition, Create an approval (V2) all return a blank white page as indicated by @StevenAtSAS

I am experiencing the same problem described by @StevenAtSAS. When I click on the Settings option, I am redirected to am empty screen. I hope that this problem gets fixed soon.


Thank you!


I filed a support ticket with Microsoft. A tech asked me to reproduce the problem and they have a Fiddler trace of what the website / web traffic is doing when the button is clicked. I'll update as things progress.

Same issue for me.  Tried both IE and Chrome.

Verified that the dialog box now shows.  Looks like this bug has been fixed as both myself and others (in related threads) are reporting they're able to access the step settings dialog box.
