[SOLVED] J4: Error massage "exif_read_data" function is not available

I understood that you have downloaded pkg_jem4beta4..zip from github.com/jemproject/JEM-Project/tree/JEM-for-Joomla-4 (to have the same version reference).
Envioroment:
- Joomla 4.0.3 with PHP 8.x without JEM (noJEM table in database)
- Install JEM4b4
- Create a new category (backend)
- Create a new event (from backend, without image, only title andcategoryselected) ---> Save ---> Error

For me, I can't reproduce it. I have no errors.
I have tried it with add image for the event, same result, no errors.

Tell me, it is right or you could give me some details (some change in the setting) or steps that I have not done or do not have.

Envioroment:
- Joomla 4.3.1 with PHP 8.x without JEM (noJEM table in database)
- Install JEM4b4
- Create a new venue (backend) without image —> no errors
- Add an image to the venue —> error on front end
- Create a new event (backend) without image —> no errors
- Add an image to the event —> error on front end
- error is visible in the front end if I open the the event
- if I remove the image —> no error any more

Sorry, I mean 4.3.0 or 4.3.1,
I try to simulate the error. Thanks for your indication.

To see the error... Open the event, what frontend view from?

I can't simulate the error, it works for me.
Five things/questins:
- Tell me the JEM view parent (frontend) open the event.
- Do you have with others image?
- What's filename image (very long, any special character)?
- Could you attach the image file?
- In the images\jem\events\small folder: Has 100x100 new file been created from the uploaded image for the event?

- Tell me the JEM view parent (frontend) open the event. --> Menu Item : 'Venues' or 'menu Simple list' or click on an venue in the Venues
- Do you have with others image? --> Tried several images. See attachments
- What's filename image (very long, any special character)? Current file name: ''spiegelplas_kaart.jpg'' after uploadd 'spiegelplas_kaart_334972965.jpg'
- Could you attach the image file? --> See attachment
- In the images\jem\events\small folder: Has 100x100 new file been created from the uploaded image for the event? --> This folder is empty!
