I have created a PDF template, but when I try to print a PDF from a quote, I receive the following error:
Notice : Undefined index: None in C:\xampp\htdocs\SuiteCRM8\vendor\tecnickcom\tcpdf\include\tcpdf_colors.php on line 260
TCPDF ERROR: Some data has already been output, can’t send PDF file
It looks like that is part of an ongoing issue:
In theory by github this problem is already solve, but i having the same problem on 2025 an i cant found and solution, do you found it?
What is your SuiteCRM version? Did you upgrade recently? Check config.php file to verify your PDF engine.
On “composer.json” i have ““tecnickcom/tcpdf”: “^6.4”,”
SuiteCRM versión 7.14.6, i recently install it from 0. But before i used 7.8.23, what i have to check of PDF Engine? " “tecnickcom/tcpdf”: “6.2.|6.3.”
“tecnickcom/tcpdf”: “6.2.|6.3.|dev-main”" it?
I use php 8.2
okay, in the root directory: config.php
‘pdf’ =>
array (
‘defaultEngine’ => ‘TCPDFEngine’,
),
Yes, it is already like this:
‘pdf’ =>
array (
‘defaultEngine’ => ‘TCPDFEngine’,
),
and the problem in logs is;
[Mon Jan 13 14:33:02.801604 2025] [proxy_fcgi:error] [pid 300909] [client 192.168.31.11:54334] AH01071: Got error ‘PHP message: PHP Warning: Undefined array key “None” in /var/www/crm/vendor/tecnickcom/tcpdf/include/tcpdf_colors.php on line 260’, referer: http://crm.compelect.com.co/index.php?action=ajaxui
I don’t know if this is correct solution.
composer update tecnickcom/tcpdf
The problem was in the code, i had to change the code of GeneratedPDF.php
generatePdf.zip (4.0 KB)
Can you copy and paste code here? 
Basically i added “ob_start();” after <?php and “ob_clean();” before the part that start to generate the pdf, and another things but thoes is not necessaries, just with this two options is suffienct to fix the problem
