…x booking location schema - calendars.ts: use nested bracket-notation query params (calendarsToLoad[0][credentialId], etc.) as required by the Cal.com v2 busy-times controller, instead of flat credentialId/externalId - api-client.ts: decode %5B/%5D back to literal brackets in URLs so NestJS parses nested params - api-client.ts: extract error messages from both body.message and body.error fields - tool-helpers.ts: include full API response body in error messages so MCP clients can debug 400s - bookings.ts: change location schema from string|object to object-only per OpenAPI spec, with description listing all 8 valid location types - register-tools.ts: improve get_busy_times tool description with clearer workflow and date format - Updated tests to match new bracket-notation params and error handling behavior Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
credentialId/externalIdinstead of the nestedcalendarsToLoad[0][credentialId]/calendarsToLoad[0][externalId]format that the Cal.com v2 controller expects. Also added bracket-decoding inbuildUrlsoURLSearchParamsdoesn't percent-encode [/]."Error 400: Cal.com API error (400)"with no details. Now the full response body is included, and error messages are extracted from bothbody.messageandbody.errorfields.to object-only with a description listing all 8 valid types.
