Source_Metadata = [
arcpy.GetParameterAsText(0)]

what is the parameter string's value? The error suggests it doesn't like it

thank for your return

Source_Metadata = [
arcpy.GetParameterAsText(0)]

this parameter it the where he can found the datalayer.

for example we can write    Source_Metadata = [C:\Users\TOTO\AppData\Roaming\Esri\ArcGISPro\Favorites\tata.gdb]

I don't see how line 11 fixed the problem, you need to throw some print or AddMessage statements in and we need to see what the output is as you progress through the script

just when i put all of the text in the same line.

so for the rest arcgisPro say :

Heure de début : vendredi 31 décembre 2021 14:17:54
valeur modifiee pour balise 1 et 2
Item: Y:\SIG-GEOSERVICES\3_OPENDATA_SIG\METADONNEES\Developpement\Metadonnees_SDE\Test_Esri.gdb\agri_MdGrosAcces
Saving updated metadata with the item...
Finished updating metadata for all source metadataA items
réussie à vendredi 31 décembre 2021 14:17:54 (temps écoulé : 0,81 secondes)

 

so for the script he do every change but in the reality the scritp don't change the valor when it is in a tag
