Then try again running your job.
Nevertheless, please note that the T-Rex Updater is not a job intended to be run manually by the users (probably we will remove this option in the future to avoid confusions) but is run automatically by the system when a new vector product is ingested into the system. On the other hand, it doesn’t harm either if you run it manually .
I have a similar error. I tried restarting the services as mentioned by Cosmin, but with the same result. What is also interesting is that I managed to upload the LPIS declarations and LUT successfully, but they are not available in the product list. If I look in the database the products are available.
I should also mention that uploading the declaration data using the graphical interface results in an error. I thought is was because of a mismatch between the cropcode from the LUT and the cropcode from the declaration data but both are integers.
