[BUG] Error: Invalid count argument

Hello @djkerya ,

This problem may appear when this module is dependant on some other module. For example, when you're using a module to create VPCs and then this module to peer them together in one Terraform run. The cause it that Terraform the data sources of this module cannot fetch required references, since those resources are not yet created. Notice, that the data sources are calculated as the first step of anu plan/apply operation.

Here is an example of how to use this module with the depends_on directive. Notice, that you have to explicitly provide references of the route tables in this case.

Hope, this helps!

It is just hilarious to close the issue independently it is solved or not. сб, 26 мар. 2022 г., 16:21 Yurii Rochniak ***@***.***>:
