@dgudkov I have find the problem, it is really simple.
When using parameters inside a module, for example my parameter "1750145273".
It will be interpreted as a number.
When using call actions from an other module to call a module, the parameter type is the type of the parent field. Even if I put a number like "1750145273" in parameter, if the field is a text, the parameter will be interpreted as a text.
My field is coming from a JSON from a webrequest, so all my fields are text.
The solution is to convert the data from text to number, before assigning parameters, or just before using expressions.
The automatic interpretation of the parameter while doing manual tests get the better of me.
I'm using EasyMorph every days, I discover little things like that everywhere !
Thank you for your help.
