When image generation fails because requirements are incompatible, identify which stage rejected the request and which requirement conflicts with it. Separate the generator's accepted inputs from the book's final artwork needs. Correct the request or production plan using the actual error and current tool documentation, then test one image before retrying the full set.
Preserve the error and the request context
Record the relevant error message, requested output, and input assets without exposing private credentials or unrelated material. Note whether the failure occurred before generation, during processing, or when importing the result into the publishing workflow. These stages can have different causes even when the user sees a general failure label.
Keep the failed attempt associated with its image slot and manuscript purpose. This prevents a later retry from losing the original task while someone experiments with settings. The record should make clear what image was needed, what was requested, and what the system actually reported.
Separate generation constraints from publication needs
List the requirements imposed by the generation tool and those imposed by the intended book format. The tool may accept particular input or output options, while the publication file needs artwork that works at its final placement. Satisfying one set of conditions does not automatically satisfy the other.
Do not treat a generator error as proof that the book's concept cannot be produced. Equally, do not remove an essential production requirement just to obtain a successful response. Determine whether the workflow can legitimately bridge the difference through a supported generation option, a revised composition, or another suitable production step.

Identify the specific conflict
Compare the request with the tool's current documented options and the actual error. Look for contradictory dimensions, unsupported combinations, incompatible reference inputs, or a mismatch between the requested output and the selected operation where those possibilities apply. Avoid assuming that every failure has the same cause.
If the message does not identify the conflict, reduce the request to a small diagnostic case while preserving its essential purpose. Change one relevant variable at a time and record the result. Repeatedly resubmitting an unchanged request provides little evidence and may create avoidable usage or duplicate outputs depending on the service.
Preserve the illustration's meaningful requirements
Distinguish negotiable presentation choices from details necessary to the book. A decorative image may tolerate a different composition, while an instructional figure must preserve the objects and relationships it teaches. Keep those requirements in the brief as you adjust technical settings.
For example, changing the aspect ratio might require rearranging objects rather than cropping away a key label or action. Review the adapted composition before approving it. A technically accepted image that no longer explains the manuscript's point is not a successful resolution of the publishing task.

Test one corrected output through the next stage
Generate or obtain one representative result using the corrected plan, then inspect it in the intended image slot. Check visible content, dimensions, and the relationship between resolution and final placement using the relevant current production guidance. Do not judge success only from the disappearance of the original error.
Keep the test bounded until the result passes the checks that motivated the request. If the next stage rejects the output, record that as a separate finding rather than hiding it under the original generation failure. The workflow needs an accepted path from request to usable book asset.
Resume the remaining work without duplication
Identify whether any usable outputs already exist from earlier attempts before retrying the queue. Associate the accepted result with the correct slot and mark obsolete attempts clearly. This reduces the chance of paying for unnecessary repeats or accidentally selecting an unreviewed alternative during export.
Save the corrected settings and the reason for the change with the asset record. Apply them to comparable requests only after checking that their requirements match. Different image tasks may need different solutions, and the successful repair of one request should not become an unsupported universal preset for the whole book.
Frequently asked questions
Clear answers for this publishing decision.
Should I keep retrying the same failed request?
First inspect the error and request state. An unchanged retry may repeat the failure or create duplicates without clarifying the cause.
Does a successful generation mean the image is ready for KDP?
No. Review the accepted image in the intended book placement and check the relevant production requirements separately.
Can I remove requirements to make the request pass?
Only adjust requirements that are legitimately negotiable. Preserve the details necessary for the image to serve the manuscript and resolve technical mismatches through a supported workflow.
What should be saved after the problem is fixed?
Keep the error context, corrected settings, accepted asset, image-slot connection, and review findings. That record supports a controlled restart without repeating the same investigation.
How do I get from an idea and a brief to an editable manuscript I can finish?
Write the brief first, generate a structure you can edit, then draft and revise the manuscript in reviewable sections so one change never overwrites work you already approved.
