Image not found or type unknown

[carlosptf]

Hello everyone,

I’m facing an issue with PDF templates in EspoCRM. I can create the template normally and add images in PNG or JPG format without any problems. However, when generating the PDF, the images are not displayed, and I encounter different issues depending on the PDF engine:
• Dompdf: displays the message: “Image not found or type unknown”.
• TCPDF: leaves a blank space where the image should be.

I’ve tried some alternatives:
• Uploading the image directly and linking to an image URL, but the result is the same.
• Checked EspoCRM logs and couldn’t find any errors related to this issue (at least in the places I looked).

Has anyone experienced this or has any ideas on how to solve it?

I can't reproduce. Please send the original image you use and export your template (and send it too).

Hello everyone,

I’ve identified the cause of the issue with images not displaying in PDF templates. Here’s what I discovered:
I created the file:

custom/Espo/Custom/Resources/metadata/app/recordId.json

with the content:

{"type": "uuid4", "length": 36}

This setup followed a tutorial I found:

https://devcrm.it/how-to-use-uuid-as-main-id-in-espocrm/

After making this change, the image code in the template looked like this:

<p><img src="?entryPoint=attachment&amp;id=d9c2fde0-68ee-4e55-8421-f2870fbc9e92" style="width: 143px;"><br><br>777<br><br></p>

When generating the PDF, this caused the error: “Image not found or type unknown” to appear instead of the image.


By removing the custom recordId.json file and reverting to EspoCRM’s default way of handling IDs, the image code changed to this:

<p><img src="?entryPoint=attachment&amp;id=677f252139bd32c 22" style="width: 143px;"><br></p>


This resolved the issue, and the error disappeared.

It seems there might be a bug in EspoCRM when handling IDs in the UUID version 4 format. Has anyone else encountered this, or should this be reported to the development team?

I already have a considerable number of records using UUID4 as the ID format. Would it cause any issues if I simply disable this configuration due to the PDF generation error?

Alternatively, is there a way to resolve the issue without having to disable the use of UUID4 IDs altogether?

only to exclude another reason: can you send the original image filename?
