Left operand, operator, right operator, type:

• Are those free-text fields or do we need to get those from somewhere? (where?)

[ds-mwesener]

We decided together with @mkanal to load the content of the dropdown fields from static file in frontend.

Tested on E2E:
Please check the error messages and fix them:

• when trying to create a policy that already exists (this is a 400 bad request instead)
• when trying to delete a policy that doesn't exist
• when trying to change a policy that doesn't exist

[ds-crehm]

Error messages will be fixed in IRS. Since this API uses the IRS responses, the error messages will be fixed here as well.
Ready for review.

[mkanal]

@ds-crehm could you please link/provide bug ticket where error message will be fixed. Thank you

[ds-mwesener]

Hi @ds-crehm I was able to fix the error responses.

Bad Request example:

Not found example:

Ready for your test, it is already installed on e2e.

[ds-crehm]

Tested on E2E-A: Looks good to me. Error messages are understandable and readable now, same as in your screenshots.
Ready for review.

There is a typo for 404 message instead "Policy with id 'abc' doesn't exists." this is correct "Policy with policyId 'abc' doesn't exist.

[mkanal]

@ds-mwesener please fix typo in 404 result message. Rest is good and ready for acceptanace.

[ds-mwesener]

Issue has been fixed. Has now same error message as IRS:

PO acceptance in behalf of @jzbmw.
Validation of policies is done in policy store and later on in frontend using policy hub.
