ADDB2C - Error to filter identities by issuerAssignedId(email) with alias

Question

I tried to make a request using the email filter; when it has +1, +2, etc., a Gmail alias, the query returns nothing.

To Reproduce:

1. Add a new e-mail on ADDB2C with an alias, for example, maria+1@Stuff .com
2. Change URI, replace xxx to your issuer: https://graph.microsoft.com/beta/users?$filter=identities/any(c:c/issuerAssignedId eq 'maria+1@Stuff .com' and c/issuer eq 'xxx.onmicrosoft.com')
3. Call URI with auth token on the headers.
   curl --location \ \--request GET 'https://graph.microsoft.com/beta/users?$filter=identities/any(c:c/issuerAssignedId eq '\''******@gmail.com'\'' and c/issuer eq '\''quartileb2c.onmicrosoft.com'\'')' \ \--header 'Authorization: Bearer {token}'
   4. See error

Answer 1

Hi @Evans Aboge , do you encounter the same problem when querying other normal users?
also, note the following guidelines when querying: https://learn.microsoft.com/en-us/graph/api/resources/objectidentity?view=graph-rest-1.0
Or try replacing '+' with '%2B' (according to Percent-encoding) to see if that works.
