Invalid Size: "

Error message

Invalid Size: "

What it means

Number-format failure in Size.parseSize: the input string has no valid 'x'/'*' separator or its numeric parts do not parse as integers. The offending string is quoted in the message; this is a malformed-input validation error.

Solutions

1. Ensure the string is in 'widthxheight' or 'width*height' form with valid integers
2. Validate/sanitize the string before parsing and fall back to a default Size on failure
