TCA manager virtual infrastructure search returns "Internal server error" with numeric only strings

Products

• VMware Telco Cloud Automation

Issue/Introduction

• In the Telco Cloud Automation (TCA) Manager UI, navigating to Virtual Infrastructure and performing a search using a string containing only numerical characters results in an "Internal Server Error". Searching with alphabetical characters or a mixture of alphabetical and numerical characters functions normally.
• The UI returns the error without generating corresponding backend log events. A network trace reveals the following API request failing with a 500 Internal Server Error:
  "GET https://<REDACTED_HOSTNAMES>/tca/vim/api/v2/orgs/default/vims?nextpage_opaque_marker=page_no=1,page_size=50,sort=tags:asc&filter=(cont,id,3509);(cont,name,3509);(cont,type,3509);(cont,creationTenantId,3509);(cont,creationUser,3509);(cont,lastUpdateUser,3509);(cont,status,3509);(cont,tcaCp.tcaCpId,3509);(cont,location.city,3509);(cont,location.cityAscii,3509);(cont,location.country,3509);(cont,vroId,3509);(cont,vroStatus,3509);(cont,nsxtId,3509);(cont,nsxtStatus,3509);(cont,location.latitude,3509); (cont,location.longitude,3509);"

Environment

VMware Telco Cloud Automation 3.4

Cause

This is a software defect in TCA 3.4 where numeric-only search strings construct a malformed API filter query containing an unhandled additional field, which triggers a server-side exception.

Resolution

• To work around this issue, ensure search strings in the Virtual Infrastructure view contain at least one alphabetical character, or utilize alternative filtering attributes.
• The permanent code fix resolving this query construction defect will be included in the VMware Telco Cloud Platform (TCP) 5.1.1 release. Upgrade to TCP 5.1.1 once available to restore numeric-only search functionality.
