ImageMagick convert-im6.q16: unable to open image - No such file or directory @ error/blob.c/OpenBlob/2874

I am having some troubles in a script with convert command in ImageMagick package.

Here is the line :

convert $dst_folder/$1/$2/$3 -resize 144x144\> $thb_folder/$1/$2/$thb_picture

where $1 and $2 are folder names (year, month) and $3 is the file name

When executing the script, i have the following type of errors :

convert-im6.q16: unable to open image `/var/www/html/piwigo/galleries/2022/03_WH/IMG-20220314-WA0010.jpeg': No such file or directory @ error/blob.c/OpenBlob/2874.

Obviously i checked that the file was there and with adequate rights:

ls -l /var/www/html/piwigo/galleries/2022/03_WH/IMG-20220314-WA0010.jpeg
-rwxrwx--- 1 www-data www-all 1663905 Mar 20 12:55 /var/www/html/piwigo/galleries/2022/03_WH/IMG-20220314-WA0010.jpeg

(the scripts in run with sudo). The -th file however is not created.

What is fun however is that the first executions of the line in the scripts often works (WA0008) ... until it starts to fail (WA0010):

if i run the scripts again, this time the file WA0010 is correctly processed

generated thumbnail IMG-20220314-WA0010-th.jpeg for IMG-20220314-WA0010.jpeg (success)

I tried to use the `-limit memory 32' option but no improvement.

Below when i used `-debug all' on WA0008 but could not conclude:

This looks like a bug in convert to me unless I am misusing it. Any idea how to solve this ?

Thanks

So finally the problem was solved by replacing

convert $dst_folder/$1/$2/$3 -resize 144x144\> $thb_folder/$1/$2/$thb_picture 

by

convert $dst_folder/$1/$2/$3 -thumbnail '144x144>' $thb_folder/$1/$2/$thb_picture

However this does not explain why I had some problem with the resize option.

Cheers
