Test Details - Xray Custom Fields no Configured

Hi Guys,

We are doing a POC of Xray for a small internal project created on JIRA before the deployment of Xray. However we occur a bug with Xray Custom fields that we are not able fix.

Indeed, if we create a new Test, the module "Test Details" is not available, as shown below :

After the input, in "Test Details" part, this warning message is displayed :

All others parts ( Test sets, Test plan etc.) are working fine. I have spent few hours in the configuration of the project and JIRA configuration without success.

Many thanks in advance,
