Hi @AntoineVDV, tbh I don't understand why it fails :/

[AntoineVDV]

@bram-odoo No idea 😅

Did you try rebasing?

[bram-odoo]

@AntoineVDV The rebase closed the PR. It's weird because the #14943 failed but the source code on saas-18.3 branch tells the opposite. Beside that, there is 0 file changed in this FW PR, I can't explain why. ¯_(ツ)_/¯
