Power Automate: Fixing True/False Condition Errors

Problem

When a Power Automate flow uses a condition that evaluates to true, the flow may fail unexpectedly if the condition is not configured correctly in the new designer.

Cause

This issue often happens when the condition expression is not set up using the correct syntax or when the visual condition builder is unable to interpret the value as a Boolean.

Fix

  1. In the condition action, switch to expression mode.
  2. Enter a valid expression that returns true explicitly.
  3. Save the condition and test the flow again.

Condition true through Expression

Alternative: Use the classic designer

If the new designer does not accept the expression, try opening the flow in the classic designer and configuring the condition there.

Set expression to true

set true in classic designer

Result

When the condition is configured correctly, the flow should run successfully and the true branch will execute as expected.

True condition true
