I am encountering an issue while attempting to migrate my application between two instances. Here are the details:
Current Process:
- Exported the app as JSON from Instance A using "Export to JSON"
- Attempted to import in the new instance (instance B) using "From JSON/ZIP" option under the create app button
Error Message Received:
"Failed import: Unable to read properties of undefined (reading 'message')"
Could you share me the guidance on resolving this error or share the correct procedure for migrating apps between instances?
When I attempted to import the app back into Instance A (the original instance), the process worked without any issues.
resources need to be named consistently across the environments or imports won't work
if you're using modules, those need to be imported first in order not to break cross-linking
On a different note best practice here would be setting up source control and migrating resources, apps, modules with that mechanism instead of doing it manually.
Hi @stefancvrkotic
Yes, I have already imported my module into those instances and just revised the resource name. However, the same error message still appears when I try to import my app.
In addition, source control is not suitable for my situation since my current app is built on a free instance, and I want to move it to one with a business license. Neither instance has an enterprise license...
In addition to the potential issues that @stefancvrkotic mentioned, it's also possible that you are missing Query Library queries. On another note, do both instances in question live in the Retool cloud? Or is either self-hosted?
Feel free to send me the JSON export of the app that you're trying to move and I'll take a look!
