I'm getting a panic error when trying to preview my stack - any ideas?
Copy code
panic: interface conversion: interface {} is string, not int

Refresh works -- but up/preview causes the error above..

can you share your code?

This looks similar to https://github.com/pulumi/pulumi/issues/5770 which was fixed recently. What provider version are you using?

v2.16.0
@billowy-army-68599 - I have a large codebase / stack. I can't share it easily.

Are you using AWS? If so, can you check that version and update to 3.19.2 which contains the fix?
sorry, 3.19.2

{     "name": "aws",     "devDependencies": {         "@types/node": "^10.17.45"     },     "dependencies": {         "@pulumi/aws": "^3.21.0",         "@pulumi/awsx": "^0.23.0",         "@pulumi/pulumi": "^2.16.0"     } }
I'll downgrade to 3.19.2 and try
which awsx is compatible ?
Different error with 3.19.2:
Copy code
fatal error: concurrent map read and map write

goroutine 1932 [running]:

This same stack works in a different environment 😕
