HTTPPOST.Exception.ErrorFindingField

Error message

HTTPPOST.Exception.ErrorFindingField

What it means

Thrown when 'URL is in a field?' is enabled and the configured URL field name cannot be found in the incoming row. data.inputRowMeta.indexOfValue() returns -1, so processRow raises a KettleException with 'HTTPPOST.Exception.ErrorFindingField' naming the field.

Solutions

1. Verify the incoming row layout (right-click the hop / 'Show input fields') and set 'URL field name' to an existing field.
2. Correct the field name casing — lookups are exact matches.
3. Reconnect/reorder upstream steps so the field actually reaches the HTTP POST step.
4. Use Fieldname selection from the dropdown in the step dialog rather than typing the name.

Example fix

// before
urlField="url_adress"; // typo, field does not exist
// after
urlField="url_address"; // matches the actual incoming field name

RowMetaInterface in = transMeta.getPrevStepFields(stepName);
if (in.indexOfValue(meta.getUrlField()) < 0)
  throw new KettleException("URL field not in stream: " + meta.getUrlField());

When it happens

Trigger: processRow executes with isUrlInField true; environmentSubstitute(meta.getUrlField()) resolved, but indexOfValue on the input row meta returns < 0 at line 379.

Common situations: Upstream step renamed or removed the URL column; field name case mismatch; environment variable substitution changed the expected name; step connected to a different stream than designed.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
