TCPDF ERROR: [Image] Unable to get image

This error message is typically associated with the TCPDF library, which is a PHP class for generating PDF files. It suggests that the library is unable to retrieve an image file that is being referenced in the code.

There are a few potential causes for this error:

• The file path for the image may be incorrect.
• The image file may be missing or corrupt.
• The server may not have permission to access the image file.
• The file format of the image may not be supported by the TCPDF library

To resolve this issue, you will need to check the file path, verify that the image file exists and is not corrupt, ensure that the server has permission to access the image, and check if the image file format is supported by the TCPDF library.
