Panic Output

Expected Behavior

It will recreate the workflow trigger from scratch again.

Actual Behavior

It fails with the error:

Stack trace from the terraform-provider-pagerduty_v3.17.0 plugin:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0xe84165]

Steps to Reproduce

Important Factoids

The workflow was created fine at first. I removed it manually to recreate it from scratch and then preparing the plan failed with the above error.

References

Are there any other GitHub issues (open or closed) or Pull Requests that should be linked here? For example:

• [Bug]: The terraform-provider-pagerduty_v3.14.4 plugin crashed! #910 Maybe?

[CristhianMotoche]

Fortunately, I managed to fix it by removing the references to pagerduty provider from the TFC state as mentioned in this post: https://support.hashicorp.com/hc/en-us/articles/30435545564307-Invalid-provider-configuration-and-unsupported-attribute-override-json

I'll close this issue for now.
