(unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

This error occurs when a string contains a Unicode escape sequence that is incomplete or has an incorrect format. The Python interpreter tries to decode the string using the 'unicodeescape' codec, which is used to decode backslash-escaped Unicode characters in a string literal. However, since the escape sequence is truncated or has an incorrect format, the decoder fails to decode the string and raises a Unicode error.

To fix this error, you need to check the string for any incomplete or incorrect Unicode escape sequences and correct them. Alternatively, you can use a raw string literal (prefixing the string with an "r") to avoid the backslash character being interpreted as an escape character. For example:

# Incorrect Unicode escape sequence
string = "Hello \uWORLD"

# Corrected string
string = "Hello \u0048\u0045\u004C\u004C\u004F"

# Using a raw string literal
string = r"Hello \uWORLD"
