+# Invalid escape sequence in Emotion tagged template
+
+#### Why This Error Occurred
+
+<!-- Explain why the error occurred. Ensure the description makes it clear why the warning/error exists -->
+
+One or more escape sequence in an Emotion tagged template was incorrect. This prevented correct parsing before transformations were applied.
+
+#### Possible Ways to Fix It
+
+<!-- Explain how to fix the warning/error, potentially by providing alternative approaches. Ensure this section is actionable by users -->
+
+Look for `\\` in the string to find the broken escape sequence(s). For example, `\\u` must be followed by four hex digits.
+
