## TL;DR

Deployments need a space, not a project: if inference works but deploy fails, set the default space and re-run. 'Software specification not found' means the base software spec changed: update the config to a current spec. REST 400 errors about version mean the version query param is missing or invalid: pin a date like ?version=YYYY-MM-DD that matches your payload. 'No project or space id provided' means you never set the default scope: call set default project or default space, or pass project_id/space_id to the foundation model object.

## Fix

1. Deployments need a space, not a project: if inference works but deploy fails, set the default space and re-run. 'Software specification not found' means the base software spec changed: update the config to a current spec.
   Expected: You see the expected output instead of the problem.
2. REST 400 errors about version mean the version query param is missing or invalid: pin a date like ?version=YYYY-MM-DD that matches your payload. 'No project or space id provided' means you never set the default scope: call set default project or default space, or pass project_id/space_id to the foundation model object.
   Expected: You get the expected result; the problem is gone.

## When to use

- You are setting up or using this watsonx.ai deployment fails feature.
- The symptom matches: project vs space, software spec, and version param.

## When NOT to use

- Unrelated watsonx.ai deployment fails issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Compatibility

Reported against watsonx.ai deployment fails.

## Variant phrasings

### project vs space, software spec, and version param

## Why it happens

Local invoke works but deployment fails: three scope and config mismatches to check.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
