Google Analytics 4 (GA4) PRO Json Export Options: Invalid container_id

Hello,

we generated the Json for Variables, Triggers and Tags in settings WeltPixel > Google Analytics 4 Ecommerce > JSON Export Options, filled in our Public ID and uploaded the JSON-File in GTM. If we upload the file in the Tag Manager settings, there is this error:

Invalid container_id (base 10 number expected): 'GTM-XX0XXXX'. (ID changed)

Is there anybody, who knows this error ? Are there any solutions for it?

Best reguards
