Problem loading a global variable in a new page- AL code

Hi everyone,

I've just created an extension, that works perfectly into my docker, both in windows and web client.
But when deploying the extension into a cloud installation, I'm finding a problem.
In one of the pages, I have defined a global variable, That global variable is shown in the page.
While I confirm different lines of that page, I'm doing some calculation, and the result of those calculation is laoded into the global variable, and must be shown into the page. But the value of the variable is not changing.
AS I've said before, in the docker this issue is working perfectly.
May be I should add a new property into the variable ort the page itself?
Thak you very muc
